In the dimly lit computer labs of the 1960s, a programmer might have clutched a stack of punch cards like a novelist holds their manuscript — a collection of instructions that, once fed into a whirring mainframe, would either bring life to an algorithm or collapse it with a single misplaced hole. Fast forward to today, and we’re watching AI generate entire applications in minutes. The journey between those two realities is more than just a story of faster machines. It’s about how the act of creating software has transformed from a mechanical chore into a deeply creative, collaborative process between humans and machines. Early programming was a gritty, physical task. There were no editors, no compilers with squiggly red lines telling you what went wrong. You wrote code for the machine…  ( 7 min )

GitHub Homepage As a junior computer science student, I have encountered various frameworks during my web development learning journey. From traditional Apache to modern Node.js, each framework has its unique advantages and limitations. Recently, I discovered an impressive Rust web framework whose performance made me reconsider the design philosophy of web servers. Throughout my learning experience, I found that traditional web frameworks often face performance bottleneck issues. Taking Apache as an example, while it is powerful and stable, its performance in high-concurrency scenarios is not ideal. I once conducted a simple performance test where Apache's average response time for 10,000 requests reached 300 microseconds, and in some complex scenarios, it even exceeded 2,500 microseconds.…  ( 9 min )

If you’ve been writing Go for a while, you might have run into a strange situation where a variable doesn’t seem to hold the value you expect. You check your code, and the logic looks fine, but something feels off. This is often caused by variable shadowing, a subtle issue that doesn’t cause a compiler error but can definitely cause confusion. Variable shadowing happens when you declare a new variable with the same name as an existing variable in an inner scope. The new variable takes precedence in that smaller scope and hides the outer one. So, any reference inside the inner scope uses the new variable instead of the outer one. Think about it like this: if you name your child after yourself, inside your house the name refers to the child even though you both share the same name. package m…  ( 7 min )

In today’s digital world, small businesses face many of the same cyber threats as large corporations.

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane My fascination with asynchronous programming began during a project where our synchronous web server could barely handle 100 concurrent users. The blocking I/O operations created a bottleneck that no amount of hardware could solve. This experience drove me to explore asynchronous programming patterns that could transform our application's scalability and performance characteristics. The paradigm shift came when I realized that asynchronous programming isn't just about performance—it's about fundamentally rethinking how applications handle concurrent operations. My research revealed a framework that demonstrates how sophisticated async patterns can be both powerful and intuitive, enabling developers to build highly concurrent appli…  ( 12 min )

Unit testing is one of the most reliable ways to ensure software correctness, yet many developers either skip it or find it difficult to integrate into their workflow. While the concept is simple—test individual units of code in isolation—the practical side of it often creates friction. Let’s break down the common challenges developers face when writing unit tests and explore how a purpose-built VS Code extension can make the process significantly smoother. Writing comprehensive unit tests requires a deep understanding of the code and the ability to think of every edge case. Developers often postpone testing because they’re under pressure to deliver features quickly. Flaky tests—those that fail intermittently without changes in code—erode trust in the test suite. They make debugging harder…  ( 6 min )

With cloud storage and high-speed internet everywhere, offline file sharing might sound outdated. But as a developer, I’ve learned it still has a place in our workflows. During hackathons, client site visits, or when working in areas with poor connectivity, being able to transfer files directly between devices — without relying on the internet — can save hours. Whether it’s large media assets, test builds, or entire project folders, a quick local transfer can be faster and more secure than uploading to the cloud. I’m curious — do you still use offline file sharing in your work? If yes, what tools or methods do you rely on, and why?  ( 5 min )

In modern C#, writing clean and readable code is more important than ever. Tuple Deconstruction. Introduced in C# 7.0, it allows you to unpack multiple values directly into separate variables in a single line — making your code shorter, cleaner, and easier to understand. Tuple Deconstruction lets you unpack the values of a tuple directly into separate variables, without having to access .Item1, .Item2, and so on. It makes your code cleaner, more readable, and often more efficient. (string name, int age) GetUser() => ("Ali", 30); var (n, a) = GetUser(); Console.WriteLine($"{n} - {a}"); // Output: Ali - 30 Here, GetUser() returns a ValueTuple, and we immediately unpack it into (n, a). var (userName, userAge) = GetUser(); var (name, _) = GetUser(); // Only get the name var users = new List { ("Ali", 30), ("Sara", 25) }; foreach (var (name, age) in users) { Console.WriteLine($"{name} - {age}"); } public class User { public string Name { get; set; } public int Age { get; set; } public void Deconstruct(out string name, out int age) { name = Name; age = Age; } } var u = new User { Name = "Reza", Age = 28 }; var (n, a) = u; Console.WriteLine($"{n} - {a}"); ValueTuple → struct-based, faster, supports deconstruction. System.Tuple → class-based, immutable, no built-in deconstruction. Tuple Deconstruction is: Cleaner and more readable Great for methods returning multiple values Useful for logging, loops, and combining multiple data points Pro Tip: Combine Tuple Deconstruction with discard variables (_) and pattern matching to write concise, expressive C# code.

Git is the lifeblood of modern software development. From hobbyists working on personal projects to massive organizations managing enterprise codebases, Git provides the version control backbone. While the learning curve can be steep at first, most developers quickly become familiar with a handful of commands and workflows. But Git is far richer than what most of us use on a daily basis. Did you know Git has over 150 commands available through its CLI? That number jumps even higher if you count all the flags, aliases, and plumbing commands under the hood. Most developers only scratch the surface using perhaps a dozen commands regularly. That's fine for basic workflows, but understanding some of Git's lesser known capabilities can help you become more effective, avoid pitfalls, and better …  ( 7 min )

Microsoft Excel has been a staple in the world of business analytics for quite some time, providing a user-friendly and adaptable platform for managing and interpreting data. While it may not be a dedicated statistical software, Excel’s powerful features make it an invaluable tool for predictive analysis and data-driven decision-making—particularly for small to medium-sized businesses. Strengths of Excel in Predictive Analysis ease of use. Most professionals are already comfortable with the interface, which means they can dive right in without a steep learning curve. Its built-in functions—like regression analysis, trend lines, and forecasting tools—enable users to spot patterns and predict future outcomes with ease. Plus, Excel’s visualization capabilities through charts, pivot tables, and conditional formatting make it simple to share predictive insights in a clear and engaging way. The ability to connect with other data sources and automate tasks using macros also boosts its analytical power. Weaknesses of Excel in Predictive Analysis large datasets, leading to slower performance and making it tougher to catch errors. While its statistical features are sufficient for basic forecasting, they don’t offer the depth found in specialized analytics tools like R, Python, or Power BI. Additionally, Excel is susceptible to human error from manual data entry, and it doesn’t natively support advanced machine learning models or automated predictive workflows without considerable customization. Excel’s Role in Data-Driven Business Decisions bridge between raw data and strategic decision-making. Businesses can leverage it to consolidate datasets, conduct scenario analyses, and create forecasts that inform budgeting, inventory management, and sales strategies. While it may not be the ultimate solution for every analytical need, its versatility and accessibility make it a go-to choice for many organizations.  ( 6 min )

Core Node.js Concepts What is Node.js, and how is it different from traditional server-side technologies? Node.js is a JavaScript runtime built on Chrome’s V8 engine that runs JavaScript outside the browser. It uses an event-driven, non-blocking I/O model, making it lightweight and efficient. Unlike traditional servers (PHP, Java), it’s single-threaded and relies on asynchronous callbacks instead of multi-threading for concurrency. Explain the event loop in Node.js. The event loop is a mechanism that handles asynchronous callbacks. It continuously checks for pending events and executes their callbacks in different phases (timers, pending callbacks, idle, poll, check, close). This allows Node.js to handle many requests with a single thread. What are callbacks, and why are they used? Callb…  ( 7 min )

Why I decide to built a better DeepSeek to PDF Converter Hey everyone! I ran into the problem of exporting DeepSeek chats to PDF, looked at existing solutions, and realized that everything currently on the market is half-baked, even though there's clear demand for this solution. All the top extensions right now can only convert chats into images and then put them into PDFs, which is inconvenient because you can't select text, and the text cutoffs at page breaks are the main pain point of such solutions. So I decided I needed to make my own. I opened Cursor, googled some libraries, found html2pdf and thought "This is it! We'll make it nice now." But I quickly realized I was just going down the same path as everyone else. All html2pdf does is convert an HTML page to canvas and then add it to PDF. The result is crooked, slanted and ugly. I decided to do PDF export on the server using another library that spins up its own headless Chrome for PDF export. Does it work? Yes. Is it convenient for users? Yes. Will it cause scaling problems in the future? Also yes. Not an option. It turns out that the same library doesn't need to spin up a separate Chrome at all - you can just extract its core and connect to the user's browser through Chrome's built-in debugger. After a couple hours and several rebuilds, it happened - DeepSeek to PDF Fully client-side, without awkward text cutoffs, without hacky image insertion into the code. A full-fledged PDF with selectable text. If anyone is facing the problem of exporting DeepSeek to PDF, I recommend trying: DeepSeek to PDF Export  ( 6 min )

Hi there! I'm Maneshwar. Currently, I’m building a private AI code review tool that runs on your LLM key (OpenAI, Gemini, etc.) with flat, no-seat pricing — designed for small teams. Check it out, if that’s your kind of thing. You’re in the middle of a Teams call with your DevOps crew when a service starts throwing alerts. Requests are piling up, some users are getting errors, and the backend logs look like they’ve been hit by a firehose. You could spin up more servers, but that’s just throwing hardware at the problem. This is where proxies earn their keep. A proxy sits between the client and the server. Instead of the client talking directly to the server, the request goes to the proxy first. The proxy decides what to do, forward it, block it, cache it, or even route it somewhere else ent…  ( 11 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane My journey into production deployment began with a catastrophic failure during our first major product launch. Our web service, which performed flawlessly in development, crumbled under real-world traffic within minutes of going live. This humbling experience taught me that deployment isn't just about moving code to production—it's about architecting systems that can handle the unpredictable nature of real-world usage while maintaining performance and reliability. The transformation in my understanding came when I realized that production deployment requires a fundamentally different mindset from development. My research into deployment strategies revealed a framework that enables sophisticated production deployments while maintai…  ( 13 min )

Let's kickoff with the first issue I remember that made me feel very dumb - configuring VPC networking for my cluster. The assessment required that I setup "a NAT gateway to manage egress traffic from the cluster, VPC networking, subnets, and firewall rules for secure communication. Like I said in my little introduction to this article series, I didn't have to think about or do any of those for my final project at AltSchool. I let Azure Kubernetess Service (AKS) handle it by default. My knowledge on setting up address spaces was weak and I had no experience with NAT gateways, so I got to googling. I came across this article on provisioning AKS and a NAT gateway with Terraform. Luckily, they also detailed their Vnet and Subnet configurations, so I tried to replicate it - which is a fancy wa…  ( 11 min )

What is Cloud Computing? Cloud computing is the delivery of computing services like storage, servers, databases, networking, software, and analytics over the internet (“the cloud”) — instead of running them locally on your own hardware. Think of it as renting a computer on the internet that you can use anytime without having to buy, maintain, or upgrade the hardware yourself. On-Demand Self-Service → Access resources when needed without manual setup. Pay-As-You-Go Pricing → Pay only for the resources you use. Scalability & Flexibility → Easily increase or decrease computing power. Global Access → Use services from anywhere in the world. Automatic Maintenance → Providers handle updates and security patches. Virtualized computing resources like servers and storage. Examples: AWS EC…  ( 6 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane My journey into TCP optimization began during a network programming course where our professor challenged us to minimize connection latency for a real-time trading system. Most students focused on application-level optimizations, but I discovered that the greatest performance gains come from understanding and optimizing the underlying TCP layer. This exploration led me to techniques that dramatically improved web server performance. The breakthrough moment came when I realized that default TCP settings are optimized for general internet traffic, not for the specific requirements of high-performance web servers. By applying targeted TCP optimizations, I achieved response time improvements of 30-40% while maintaining connection stab…  ( 9 min )

DRF, Part 2: ViewSet Overrides Welcome to the second half of our guide on DRF architecture. In Part 1, we established a clear rule: serializers are the guardians of your data. They handle validation, transformation, and representation. They ensure that the data entering your system is clean and the data leaving is well-formed. But that’s only half the picture. Viewsets handle the HTTP journey. They don't care if a start_date is before an end_date — that's the serializer's job. They care about things like: Parsing the incoming request. Checking permissions and authentication. Calling the serializer to validate data. Triggering the save operation. Formatting the final Response with the right data and status code. Let's explore the most common and powerful methods you can override. create v…  ( 9 min )

DRF, Part 1: Serializer Overrides Ask any Django developer where to put validation, formatting, and orchestration logic, and you’ll often get different answers — some say “just put it in the serializer,” others drop everything in the viewset. This works… until it doesn’t. when to override a serializer method and when to override a viewset method is key to keeping a codebase clean. Think of your serializer as the security guard at the door of your database. It's responsible for three primary tasks: Validation: Checking the ID of incoming data to ensure it's legitimate. Transformation: Making sure the data is in the right format before being saved. Representation: Deciding how the data should be presented when it's sent back out. Its world is small and focused: just the data. Let's look at…  ( 8 min )

Introduction As I wrote, C allows anonymous unions, that is a union without a name: enum token_kind { TOKEN_NONE, TOKEN_INT, TOKEN_FLOAT, TOKEN_CHAR, TOKEN_STR }; struct token { enum token_kind kind; union { // "anonymous" union long i; double f; char c; char *s; }; }; struct token t = { .kind = TOKEN_CHAR, .c = 'a' }; It turns out that C (but not C++) also allows anonymous structures. They tend to be used even less that anonymous unions, but, in a few cases, anonymous structures are just the thing. Among my previous articles, the one on Handy C/C++ Preprocessor Macros actually used an anonymous structure, though I didn’t specifically call attention to it. In that article, what was needed was a way to use static_assert in an…  ( 7 min )

GitHub Homepage As a junior computer science student, I gradually recognized the importance of asynchronous programming during my web development learning process. Traditional synchronous programming models often cause thread blocking when handling IO-intensive tasks, while asynchronous programming allows programs to continue processing other tasks while waiting for IO operations. Recently, I deeply studied a Rust-based web framework whose asynchronous programming implementation gave me a completely new understanding of this technology. In my previous projects, I used traditional synchronous programming models. While this model has clear logic, it encounters serious performance bottlenecks when handling large numbers of concurrent requests. // Traditional synchronous programming example @R…  ( 10 min )

INTRODUCTION Microsoft Excel is one of the most widely used tools for analyzing data and making predictions. From sales forecasting to budget planning, it offers businesses a quick and accessible way to turn raw numbers into insights. But while Excel is powerful, it has both strengths and limitations in predictive analysis. User-Friendly– Simple interface for quick forecasting. Built-In Tools– Functions like FORECAST.ETS, TREND, and regression in ToolPak. Cost-Effective– Already installed in most offices. Versatile– Handles various file formats and datasets. Limited Data Capacity – Slows with large datasets. Error-Prone – Manual entry mistakes can distort predictions. Basic Models Only – Lacks advanced AI or machine learning features. Collaboration Issues – Version control can be challenging. Role in Business Decisions Excel is excellent for quick “what-if” scenarios, trend analysis, and creating visual reports for decision-makers. It works best as a starting point before moving to advanced tools like Power BI, Python, or R for deeper analysis. Excel remains a reliable tool for small-to-medium data predictive analysis, offering speed, accessibility, and clear visualizations. However, for large datasets and complex models, businesses should complement Excel with more advanced analytics platforms to achieve accurate, data-driven decisions.  ( 5 min )

Programming Rules & Key Concepts Date: 10/08/25 Day: 16 Special Class Learnings Today’s class was packed with valuable programming fundamentals and practical insights. Here's a summary of everything I learned today — from basic programming rules to essential coding techniques and even resume-building tips! Here are some beginner-friendly programming rules I noted down, which are helping me build a strong mindset when solving problems: Don’t say "I don’t know" — say "Let me try." Don’t think about the entire output at once. Think about each step carefully. Make it repeatable as much as possible. Introduce variables if you think it is necessary. Go from micro to macro. Go from known to unknown. These rules help break down complex problems into manageable pieces — and that's the key to learning programming effectively. Decimal Hexadecimal Octal Understanding these systems is important for data conversion, memory addressing, and low-level operations. How to square a value: n**2 or pow(n, 2) How to cube a value: n**3 or pow(n, 3) 🔁 Division Operators: / (Division) — returns float 10 / 3 = 3.33 // (Floor Division) — returns whole number without decimal 10 // 3 = 3 🔄 Number Reversal: Learn how to reverse digits in a number using loops or string slicing. If the number is 4563, the outputs can be: 63 56 45 This can be done using loops and string slicing or integer division with modulo. Using cout / print() Basic addition of numbers Palindrome check How to build a resume How to prepare for interviews How to partition the resume (technical, academic, project-based) Today’s class gave me a solid understanding of programming logic and job preparation strategies. I’m excited to continue my journey and keep sharing my learnings here. If you're also a beginner, I hope this helps motivate you to stay consistent and curious. Happy coding ✨️  ( 6 min )

Introduction Let's Get Our Hands Dirty! This guide is interactive you’ll read, you’ll type, you’ll feel powerful. PostgreSQL (or Postgres) is a free, open-source, object-relational database that powers web apps, enterprise systems, and even scientific research. In short if you’ve got data, Postgres can handle it. So before we jump in, ask yourself: Do you have terminal access (with sudo)? Are you working on a fresh Linux install or an existing server? Do you know how to copy paste without breaking things? If your answers are mostly “yes,” then high five! “The best way to learn is to do. So open that terminal we’ve got some commands to run.” System Update Command: 1. System UpdaCommand: sudo apt update && sudo apt upgrade -y This command updates your system package list and installs the latest versions of all packages. It ensures your system is ready for PostgreSQL. bash Install PostgreSQL Switch to PostgreSQL User and Access Shell Set PostgreSQL Password Create Database and User sql Edit Config for Remote Access Command: sudo nano /etc/postgresql/14/main/postgresql.conf Command: sudo nano /etc/postgresql/14/main/pg_hba.conf Restart and Check Status Command: sudo systemctl status postgresql You’ve now successfully installed and set up PostgreSQL on your Linux server. With just a few commands, your system is ready to store, manage, and query data efficiently. PostgreSQL is powerful, secure, and ideal for both small projects and large applications. Keep exploring its features to get the most out of your database setup.  ( 6 min )

I get asked how I "do so much" sometimes when I meet people in the context of starting new side projects, releasing opensource libraries, or being active in a community. None of this is prescriptive -- everyone has to decide what they want for themselves, but I have self-reflected on this question a decent amount. But, first a caveat: one lesson I have learned over time is to try to not judge myself compared to others -- especially those I do not know well. I have gone through seasons of my life (a term I first heard on a Startups for the Rest of Us podcast a long time ago) where I mostly consumed instead of created. I have taken sabbaticals where I did not think about or write any code at all. I have taken vacations where I have completely disconnected from the digital life. To me, that's…  ( 9 min )

Picture yourself in a technical interview at LinkedIn. The interviewer sketches a binary tree on the whiteboard and asks, "How would you find its height?" This seemingly simple question is actually testing several important concepts: your understanding of tree structures, recursive thinking, and edge case handling. It's a classic warm-up problem that I've seen countless candidates either ace or stumble on, depending on their preparation. The height of a binary tree problem appears frequently in technical interviews because it tests fundamental skills that transfer to more complex tree problems. Companies like LinkedIn, Microsoft, and Google often start with this question before moving to harder tree manipulation problems.

Each framework has its unique design philosophy. Recently, I discovered an impressive web framework that adopts a completely different design philosophy—zero-dependency design. This minimalist design philosophy made me reconsider the essence of software architecture. In my previous project experience, dependency management has always been a headache. Taking a typical Spring Boot project as an example, even the simplest "Hello World" application requires introducing numerous dependencies. org.springframework…  ( 10 min )

Its powerful ownership model ensures safer code, which is vital when m…  ( 7 min )

It’s been easy to miss just how quickly the centre of gravity in AI has started to drift away from the cloud. Scroll through any recent handset launch and you’ll see phrases like “Gemini Nano on-device” or “runs local LLMs” wedged between megapixel counts and battery stats. Google’s latest Pixel 9 line, Samsung’s S24 family and even the mid-range Galaxy S24 FE can now execute a trimmed-down Gemini model entirely on the handset, with no round-trip to Mountain View required. Yesterday I borrowed a colleague’s Z Flip 7 and watched it transcribe and translate a Spanish conversation on the tiny cover screen using Gemini Live - five years ago that would have taken a server farm; today it happens in your pocket. This shift is happening everywhere you look. Hobbyists are coaxing full LLaMA deriva…  ( 10 min )

(Първо публикувано на 29.01.2017) Днес ще се позанимаваме с нещо малко по-различно — обхождане на двоични дървета. Няма да се спирам върху обяснения на това какво е двоично дърво — в книгата на Светлин Наков е обяснено прекрасно. Там е обяснена цялата терминология, която може да срещнете в този пост. Тъй като последните няколко поста бяха за алгоритми от категорията “разделяй и владей”, може да се учудите, но и този спада към тях. Причината е, че двоичното дървото като структура включва корен, ляво поддърво и дясно поддърво (т.е. частта “разделяй” е в самата й дефиниция). Това подсказва, че обработката на такива дървета ще използва именно подхода “разделяй и владей”. Нека да видим за какво иде реч. 😀 Трудно беше да избера картинка за този пост, но тази е непобедима… :) ОПИСАНИЕ: “Обхожда…  ( 11 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane During my final year project on microservices architecture, I encountered a critical challenge that many developers face: dependency bloat. Our team's initial implementation relied on dozens of external libraries, creating a complex web of dependencies that introduced security vulnerabilities, increased binary size, and complicated deployment processes. This experience led me to explore a radically different approach that would fundamentally change my perspective on web framework design. The revelation came when I discovered that most web framework dependencies provide functionality that can be implemented more efficiently using only standard library components. My research into zero-dependency architectures revealed performance b…  ( 9 min )

Many aspiring programmers make a common mistake: they jump straight into complex code without understanding the fundamentals. This approach often leads to confusion and gaps in knowledge. If you want to succeed in IT and adapt to different programming languages as the industry evolves, you need a solid foundation in programming and computer basics. Let me walk you through these fundamentals in a way that makes sense. Understanding Your Computer The processor is like the brain of your computer. Whether you’re streaming music, making a phone call, or running an app, the processor handles all these tasks. Here’s what makes it special: How Processors Work OFF (representing 0) The Language Challenge This created a communication problem that the computing world solved through evolution. The Evolution of Programming Languages 1. Machine Language (1940s) Example: 10110000 01100001 (this actually means "move the value 97 into a register") 2. Assembly Language (1950s) ADD for addition 3. High-Level Languages (1950s-1960s) print("Hello World") The Translation Process Take your human-readable code Why This Foundation Matters All programming languages eventually become machine language Learn any programming language more effectively Understand why certain programming concepts exist Debug problems by thinking about what’s happening “under the hood” Adapt as new technologies and languages emerge Remember: programming languages are tools. The real skill is learning to think logically and break down problems into steps a computer can follow. Master these fundamentals, and you’ll find that picking up new languages becomes much more manageable.  ( 7 min )

This is a submission for the Redis AI Challenge: Beyond the Cache. In today's connected world, monitoring critical infrastructure like water systems, power grids, or server farms is a monumental task. A single failure can be catastrophic. The challenge is detecting problems the instant they occur, not minutes later when a traditional database finally runs its report. I built FastMap, a real-time anomaly detection platform for large-scale sensor networks. It provides a live map-based dashboard where operators can monitor thousands of IoT sensors at a glance. When a sensor reports an anomalous value, like a sudden pressure spike or temperature drop, FastMap identifies it in milliseconds and instantly flags the sensor on the map, allowing for immediate intervention.

GitHub Homepage As a junior computer science student, I have encountered various frameworks during my web development learning journey. From traditional Apache to modern Node.js, each framework has its unique advantages and limitations. Recently, I discovered an impressive Rust web framework whose performance made me reconsider the design philosophy of web servers. Throughout my learning experience, I found that traditional web frameworks often face performance bottleneck issues. Taking Apache as an example, while it is powerful and stable, its performance in high-concurrency scenarios is not ideal. I once conducted a simple performance test where Apache's average response time for 10,000 requests reached 300 microseconds, and in some complex scenarios, it even exceeded 2,500 microseconds.…  ( 9 min )

Week 10 started with a very clear plan. Me and Hardik had a meet to decide what to do for the simulator issues and in which order: Download Image User Manual Discussion Forum Themes Simple. Clear. Easy. But then… me being me… I saw another bug and just couldn’t resist. Sorry, Hardik. While working on the simulator, I stumbled upon something that kept bugging me. When you try to edit a project you created: The UI wasn’t uniform. The tag input field had no instructions on how to add multiple tags. Even worse — you update the project, then try to re-edit it… and all your previous details are gone. You’d have to write from scratch. So I fixed the persistence issue first — now, when you re-edit a project, your details are still there. But then I saw another thing: tags weren’t even showing…  ( 7 min )

In the fluorescent-lit war rooms of enterprise cybersecurity, a fundamental shift is underway.

Listeners of Threshold Cryptography Bootcamp were (t)asked to reflect on the first four sessions we got to this date. I guess the most of approaches to the task will be a (LLM-)conspect of the lectures, and I don't want to join this chorus since there's quite a number of threshold crypto guides and I can only produce a worse one. Instead let me think out loud on comparison of the threshold approach and naive multisig. I mean the nature of the lectures advertises the first one quite heavily and as a natural (for a cryptography engineer) skeptic push-back I was constantly tried to think how the things could be done (and often are done currently) without thresholds. By multisig I mean just counting the signatures on something which obviously can solve the very same problem: to require $t$ out…  ( 7 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane My understanding of middleware architecture evolved during a complex project where we needed to implement authentication, logging, rate limiting, and CORS handling across dozens of API endpoints. Initially, we duplicated logic across handlers, creating a maintenance nightmare. This experience led me to explore middleware patterns that could elegantly solve cross-cutting concerns while maintaining performance and flexibility.

My research revealed a framework that implements middleware patterns with exceptional performa…  ( 11 min )

AI tools are now in every creator’s toolkit — scripting, visuals, editing, even voiceovers. But YouTube’s July 2025 policy change has everyone asking: Can you still monetize AI-generated videos? The answer is yes — if you do it right. Smart AI Drop, and here’s what I’ve found. In 2025, YouTube replaced the “repetitious content” label with “inauthentic content” — a move to target fully automated, low-effort videos. AI voices + stock footage + no human value? ❌ AI-assisted scripts + human narration + unique editing? ✅ From my breakdown: Add human presence — voice, face, or personal commentary. Curate AI outputs — never post them raw. Edit creatively — storytelling, pacing, and visuals matter. Disclose synthetic media when it’s realistic. When I tested this with examples from my research at Smart AI Drop, I noticed something interesting — even channels that looked “safe” got flagged because they relied too much on automation. Adding a short on-camera intro or personal insight often fixed this. If you’re building a channel in 2025, AI can accelerate your workflow — but it won’t carry you past YouTube’s manual review unless you keep the human touch. My complete workflow, example breakdowns, and monetization-safe AI tools are all covered in detail on my blog. If you’re serious about using AI for YouTube and want the exact strategies I use, I’ve posted the full guide on my blog — just search “Smart AI Drop” and look for the 2025 YouTube AI Monetization Guide.  ( 6 min )

I used Tailwind built-in classes such as : flexand justify-center for alignment w-3 h-3 bg-black rounded-full for perfect dots gap-1 and p-2 for spacing and created 6 faces as follow: const Face = ({ value }: { value: number }) => { switch (value) { case 1: return ( …  ( 7 min )

Firebase cloud databases, and in particular Firestore, are seen as a convenient tool for building simple applications that use data from the internet. They are well-suited for quickly testing hypotheses, providing a ready-made server infrastructure and an easy-to-use SDK for client platforms. However, what if this SDK deviates from the paradigms we have established in our project? Let's take a look at how you can use Firestore through the REST API. This can be done using your existing stack. For example, in my Android project, I used Retrofit, Coroutines, and more. Additionally, you can work with the RPC API as well. To work with Firestore in this way, you do not need dependencies on Firebase services. Firestore itself says that using the REST API is just in case you don't want to drag the…  ( 7 min )

By Muhammed Shafin P (@hejhdiis) In today’s world, cybersecurity threats are becoming increasingly sophisticated and persistent. Relying on a single security tool or method is no longer sufficient to protect sensitive corporate data and systems. Organizations must adopt a defense-in-depth strategy, combining multiple layers of security to reduce the risk of successful attacks. This article explores a concept that integrates several advanced security techniques into one cohesive system to minimize hacking risks. The core idea involves strict separation of data storage and execution environments. Data such as emails, documents, and other sensitive information is stored on dedicated servers designed to only hold data without the ability to execute any code. This non-executable storage layer s…  ( 7 min )

In the given example, we created a Global Temporary Table (GTT) named session_transactions using the ON COMMIT PRESERVE ROWS clause. This setup ensures that the data inserted into the table remains available throughout the entire database session, even after a COMMIT is issued. This is particularly useful in real-time scenarios like banking applications, where multiple transactions (credits or debits) are temporarily recorded during a user’s session for validation, batch processing, or reporting. Each session maintains its own copy of data, providing data isolation between users. The inserted rows will stay intact across commits until the user ends the session or logs out. Once the session ends, the data is automatically deleted, ensuring no residual data persists. This behavior helps in m…  ( 6 min )

Table of contents Variance in Generics Covariance Contravariance Invariance References Variance in generics refers to how subtyping relationships behave when they are wrapped in a generic container or function. E.g. if Cat is a subclass of Animal, then subtype polymorphism which you may already be familiar with, explains how a Cat can transform (morph) into, and be used in place of an Animal. In a similar way, variance tells us how e.g. a set[Cat] can transform (vary) and be used in place of a set[Animal] or vice versa. There are three types of variance: Covariance enables you to use a more specific type than originally specified. Example: If Cat is a subclass of Animal, you can assign an instance of Iterable[Cat] to a variable of type Iterable[Animal]. Contravariance enables you to u…  ( 16 min )

Original post: Convert a PEM File to a PPK File Using PuTTY In this tutorial, you’ll learn how to convert a .pem file into a .ppk file using PuTTY on Windows. This process is often needed when connecting to AWS EC2 instances or other servers via PuTTY, as PuTTY requires keys in .ppk format rather than .pem. We’ll go step-by-step, from downloading PuTTY to saving the converted key, so you can start connecting securely without errors. Visit the official PuTTY website to download the installer. Once downloaded, run the installer and follow the prompts to complete the installation. After installation, search for PuTTYgen in your Start Menu and open it. On the PuTTYgen home screen, under the Actions section, click Load to load an existing private key file. A file explorer window will open. At the bottom right corner, change the file type filter from PuTTY Private Key Files (*.ppk) to All Files. Select the .pem file you want to convert and click Open. After selecting the file, you should see the following message: Successfully imported foreign key (OpenSSH SSH-2 private key (old PEM format)). To use this key with PuTTY, you’ll need to click Save private key to save it in PuTTY’s format. Under the Actions section, click Save private key. You may see a warning: PuTTYgen Warning Are you sure you want to save this key without a passphrase to protect it? Click Yes (unless you want to add a passphrase). Choose a filename for your .ppk file and click Save. You have now successfully converted your PEM file to a PPK file and can use it with PuTTY.  ( 6 min )

When a React app grows, bundling all its code into a single file can slow down the initial load. Lazy loading solves this by splitting the code into chunks and loading parts only when needed — improving load times and user experience. What is Lazy Loading? Lazy loading (a.k.a. code splitting) is a performance optimization technique where parts of your app are loaded on demand rather than all at once. In React, we use: React.lazy() to dynamically import components. Suspense to show a fallback (like a loader) while the component loads. Basic Lazy Loading Example import React, { Suspense } from 'react'; const About = React.lazy(() => import('./About')); export default function App() { return ( My App Loading... }> …  ( 6 min )

You are probably already familiar with the FOR loop format: FOR loop_counter IN [REVERSE] lowest_number..highest_number LOOP {...statements...} END LOOP; According to this syntax, the loop counter (loop_counter) sequentially (with a step size of 1) iterates from the lowest_number to the highest_number. For example, executing the following code displays the numbers from 4 to 8: SQL> set serveroutput on begin for i in 4 .. 8 loop dbms_output.put_line(i); end loop; end; / 4 5 6 7 8 PL/SQL procedure successfully completed. If we wanted the output above to also include the numbers from 50 to 55, what changes would be necessary? begin for i in 4 .. 8 loop dbms_output.put_line(i); end loop; for i in 50 .. 55 loop dbms_output.put_line(i); end loop; end; / 4 5 6 7 8 50 51 52 53 54 55 PL/SQL procedure successfully completed. With the enhancements introduced in Oracle 21c, solving such problems has become simpler. begin for i in 4..8,50..55 loop dbms_output.put_line(i); end loop; end; / Let’s explore more of the new FOR loop enhancements in Oracle 21c through additional examples. Example (WHEN clause) BEGIN FOR i IN 1 .. 30 WHEN MOD(i,4) = 0 LOOP dbms_output.put_line(i); END LOOP; END; / 4 8 12 16 20 24 28 Example (WHILE clause) declare n number:=10; BEGIN FOR i IN 1 .. n WHILE i<n/2 LOOP dbms_output.put_line(i); END LOOP; END; / 1 2 3 4 Example (Step control) begin for i in 1 .. 10 by 2 loop dbms_output.put_line(i); end loop; end; / 1 3 5 7 9 Example (Decimal counter values) BEGIN FOR i number(10,5) IN 3.5..4.4 by 0.4 LOOP dbms_output.put_line(i); END LOOP; END; / 3.5 3.9 4.3 Example (REPEAT clause) BEGIN FOR i IN 5 LOOP dbms_output.put_line(i); END LOOP; END; / 5 Although this may not seem very useful on its own, with the REPEAT clause, it becomes more practical. begin for i in 4, repeat i*4 while i < 1500 loop dbms_output.put_line(i); end loop; end; / 4 16 64 256 1024  ( 6 min )

To solve the accidentally changed problem, anyone want to the edit group's slide would have to do this: Create a copy of the group's Google Slides file Work on that copied file Ask the leader to review Only when the leader agree that changes are merged into the group's file In order to preserve the original file, anyone wants to work on that file must create a copy of it. In the Git world, it's everyone must create a new branch. Wait, you said. If 1 people create a copy, working on it, and then the leader upload that into Google Drive is fine, but what if 3 people do it at the same time? Does the leader have to metic…  ( 13 min )

When talking about bandwidth or data transfer in the context of the web, most people think of bandwidth used by the actual webpages that you host. Thanks to a report by HTTP Archive, we know that webpages in 2025 weigh around 2.5 MB. Page Weight (source: HTTP Archive) This page weight includes everything that gets downloaded to render a page, like HTML, CSS, JS, fonts, images, and other assets. However, this does not tell the story about bandwidth used for APIs. It's tempting to assume that HTML, CSS, and JS are tiny since they are just text. However, HTML itself is bloated since you need to use markup tags, not including the attributes and more inline data. Add to that: CSS frameworks that load hundreds of KB JavaScript bundles Images, assets, fonts Tracking scripts, analytics, etc. So i…  ( 6 min )

The goal is to determine whether the digits of a given integer n can be reordered to form a power of two. The reordering must not produce a number with a leading zero. For example: n = 1 → valid (1 is 2⁰) n = 10 → not valid (digits 1 and 0 cannot form a power of two without leading zeros) You are allowed to permute the digits freely, but cannot add, remove, or change digits. The key observation is that the digits of powers of two have specific digit combinations. If we can check whether n can be rearranged to match the digits of any power of two up to 2³⁰ (since 2³⁰ is slightly over 10⁹), then we can decide whether it's valid. Instead of generating all permutations of n, we use a digit frequency encoding. The idea is that two numbers are permutations of each other if and only if they have …  ( 7 min )

I once ran into this problem of differentiating runes, bytes and graphemes while handling names in Tamil and emoji in a Go web app: a string that looked short wasn’t, and reversing it produced gibberish. The culprit wasn’t Go being flawed, it was me making assumptions about what “a character” means. Let’s map the territory precisely: Go represents strings as immutable UTF-8 byte sequences. What we see isn’t what Go handles under the hood. s := "வணக்கம்" fmt.Println(len(s)) // 21 The length is 21 bytes not visible symbols. Every Tamil character can span 3 bytes. Even simple-looking emojis stretch across multiple bytes. string → []rune( gives you code points, but still not what a human perceives. rs := []rune(s) fmt.Println(len(rs)) // 7 Here it’s 7 runes, but some Tamil graphemes (like “க்”) combine two runes: க + ். Go’s standard library stops at runes. To work with visible characters, you need a grapheme-aware library, like github.com/rivo/uniseg. for gr := uniseg.NewGraphemes(s); gr.Next(); { fmt.Printf("%q\n", gr.Str()) } That outputs what a human reads “வ”, “ண”, “க்”, “க”, “ம்”, and even “❤️” as a single unit. If your app deals with names, chats, or any multilingual text indexing by bytes will break things. Counting runes helps, but can still split what you intend as one unit. Grapheme-aware operations align with what users actually expect. Real bugs I’ve seen: Tamil names chopped mid-character, emoji reactions breaking because only one code point was taken. Task Approach Count code points utf8.RuneCountInString(s) Count visible units Grapheme iteration (uniseg) Reverse text Parse into graphemes, reverse slice, join Slice safely Only use s[i:j] on grapheme boundaries Think about what you intend to manipulate: the raw bytes, the code points, or what a user actually reads on screen and choose the right level.  ( 6 min )

About the Cover The chimera is a mythical creature composed of parts from different animals — a lion, a goat, and a serpent — fused into a single being. This fascinating blend of diverse elements serves as a powerful metaphor for Go interfaces. Coming from a language like C# or JavaScript, interfaces in Go can feel like a cruel joke. They’re not what you expect, and they don't play by the rules you're used to. This post is your survival guide to Go interfaces.* In more traditional languages, interfaces are binding contracts: you define methods in an interface, and a class in order to satisfy that interface must implement those methods. In exchange, at any point in your code where you expect that interface, you can pass any class that implements it. Let's see a quick example. We want to log…  ( 15 min )

Resource versioning is a key feature in Ci/CD Platforms. It provides developers a way to track how a pipeline has changed over time, ensuring reproducibility, stability, and traceability of builds. Conveyor CI on the other hand, doesn't have this inbuilt into it. This has therefore been a great downside of it, leading developers who might use it miss out on the above mentioned features. The design or implementation can vary depending on multiple cases like the purpose, use case, or even the internal design of the system. But at the core, you need to be able to differentiate multiple variations of the same process as it is re-triggered. This means each execution of a CI/CD process has to have a unique Identifier that differentiates it from other executions under that same resource. The most…  ( 8 min )

If you’ve ever typed a prompt into ChatGPT and wondered “How on earth does this AI understand me?” — the secret lies in vectors and embeddings. These mathematical tools allow large language models (LLMs) to interpret, compare, and generate text with astonishing accuracy. In this article, we’ll explore these concepts in depth — but in a way that blends math, real-world analogies, and some Python so you can see it in action. A vector is simply a list of numbers that places something inside a mathematical space. In school, you may have plotted points using X and Y coordinates. Add Z, and you move into 3D space. LLMs take this idea further — way further. Instead of 2 or 3 dimensions, they use hundreds or thousands. Each dimension represents some learned feature of meaning. For example, a…  ( 7 min )

This week, I worked on something exciting: reports routes for our backend. This is the part of the system that helps admins see important data at a glance. My job was to build endpoints that could transform raw learner and payment data into meaningful insights, including: A list of all learners The number of learners per track The total income The income per track In short, I wasn’t just fetching data anymore. I was shaping it into something an admin could actually use to make decisions. Pretty straightforward on paper, but here’s where the twist came in. I had to use MongoDB’s .aggregate() for the first time. Before this, I had been living in the world of .find() and .findOne(). They were my comfort zone; very simple, direct, and predictable. But for this task, I needed more power: grouping data, filtering it, reshaping fields, and running calculations all in one go. That’s where .aggregate() stepped in. One of my tasks was to get the number of learners in each track only if they had paid. With .aggregate(), I learned I could: Filter with $match Group with $group Count or sum fields using $sum Reshape or limit fields with $project Here’s a little snippet from what I wrote: const result = await learnerModel.aggregate([ { $match: { status: 'paid' } }, { $group: { _id: "$track", count: { $sum: 1 } } }, { $project: { track: "$_id", count: 1, _id: 0 } } ]); In this example, $project let me clean up the output by renaming _id to track and hiding unnecessary fields. Seeing the data come out exactly as I needed — filtered, grouped, and neatly shaped — felt so satisfying. It was like discovering that MongoDB had been quietly hiding a mini data-analytics tool inside it all along. This experience was more than just adding new routes. I learned a new way of thinking about database queries, and I’m already imagining all the other problems .aggregate() could help me solve.  ( 6 min )

About a month ago, I had this random thought while on the bus to school: “What if I could just listen to my handwritten notes instead of reading them?” I wanted something simple, cost-effective, and since I already spend a lot of time working with AWS, it made sense to build it there. After a bit of brainstorming, I landed on the perfect stack: Amazon Textract → Extract text from my images. Amazon Polly → Turn that text into natural-sounding speech.

🚀 Next Up: Vector Databases (Hands-On!) We’re about to build a tiny semantic search engine from scratch. The secret ingredient? Vector databases — a tool that’s surprisingly easy to grasp, but powerful enough to make modern AI work. By the end of this article, you’ll: Understand what embeddings are (and why they’re magic) Learn what a vector DB does Spin up Qdrant in Docker Store and search your own embeddings See how this forms the foundation for RAG (Retrieval-Augmented Generation) Step 1 — From Words to Numbers: Embeddings Computers don’t understand “dog” or “car” like we do. Instead, we turn these into embeddings — long lists of numbers that capture meaning and relationships between concepts. Example: "dog" → [0.1, 0.6, -0.4, ...] "puppy" → vector very…  ( 7 min )

[ Part One of Five ] This post is not a historical walkthrough. So… don’t look for perfect chronology here — look for clarity. Hello. This book starts with a very short introduction — short enough that I’ll just tell you about the name. It’s called bash2003. Why 2003? Because the first version of Bash was released on 08/06/1989, and if you add up those numbers (8+6+1989), you get 2003. The book has 10 chapters and is written for beginners. Each post in this series will fully cover a single concept. I won’t stretch topics over multiple posts. First, I’ll explain the idea, then provide code, examples, and exercises and so on. The goal of this book is to teach Linux by learning Bash — because I believe it’s more practical that way, I think XD. Although this section is titled “Bash, Terminal, …  ( 7 min )

The OOD Lie: Why Your Old Code Might Be a Secret Killer Hey there! Ever feel like your app is just... slow? Or maybe it crashes sometimes, and you’re scratching your head wondering why? You’re not alone. We often hear about "Object-Oriented Design" (OOD) being the holy grail of software building. And for a long time, it really was! Things like inheritance – where new pieces of code (child classes) get features from old pieces (parent classes) – seemed like a superpower. But here’s the thing: sometimes, what’s supposed to help you can actually hurt you. And in the world of app performance, that old "inheritance" trick might just be secretly slowing everything down. It’s what we call the "OOD Lie." Imagine you have a super fancy, multi-tool gadget. It does everything! Now imagine you want …  ( 9 min )

In your quest to learn machine learning, this is probably the first and simplest prediction model you will learn. Each one of these words have a meaning! Let's break it down: Linear regression attempts to model the relationship between two variables by fitting a linear equation to observer data. So, if you have two variables and they have a relationship you can use this to create a prediction model. The classic example is Housing Prices. The bigger the house is, the pricier it gets. So one variable could be Area Size and the other Price. We can use Linear Regression to predict the price of a house based on its size! Disclaimer not the best model for this prediction - it is just the simplest! When we say linear, what we mean is that it is going to fit in a linear equation. On one axis you h…  ( 10 min )

When your app is just starting out, scaling isn’t something you think about much , and one decent server usually does the job. But as traffic grows, you eventually hit a wall and have to decide: do you make your server stronger or add more servers to share the load? Let’s break down these two approaches. When we first launch an app, the traffic is usually pretty manageable. But as it becomes more popular, we might start getting way more requests than our current setup can handle. The ability to deal with this increased number of requests is known as scalability. We are essentially handling more requests by throwing “more money” at the problem. There are two common approaches to this: Vertical Scaling → Buy a bigger machine. Horizontal Scaling → Buy more machines of the same capability. …  ( 7 min )

In an era where the internet is dominated by a handful of tech giants, the emergence of artificial intelligence presents a pivotal crossroads.

We are living in what I like to call The Golden Age of Instant Gratification for Developers™. Want to build a web app? Done. AI has essentially turned us all into Tony Stark.

The Web is Breaking Under the Weight of AI. The web has always been about evolution, and now, we stand on the precipice of its next great transformation: the Agentic Web. This isn't a far-off fantasy. Researchers and engineers are already defining this new era, one where autonomous, goal-driven AI agents interact directly with each other to execute complex tasks on our behalf. The core idea is a shift from manual interaction to delegated intent; you state a goal, and a team of agents accomplishes it for you. This is the logical evolution of the internet, a more interactive and automated experience. But there’s a problem: an unspoken crisis. The Agentic Web is being built on a foundation of sand. Today's AI agents are like tourists in a foreign city who can't read the signs. They navigate…  ( 12 min )

Hey everyone, What if a simple social media site felt more like a game? What if user achievements weren't just static icons, but interactive 3D objects you could actually play with? I had this crazy idea while working on my latest project, GOAT – an open-source social debate platform. I wanted to reward users in a way that felt substantial and cool, not just another boring badge. So, I decided to build a real-time 3D rendering engine right inside my Laravel application. Live Demo: https://goat.uz/@goat https://github.com/umaarov/goat-dev It sounds a bit nuts, I know. Here’s a breakdown of how I made it work without melting the user's browser.

Hi there! I'm Maneshwar. Currently, I’m building a private AI code review tool that runs on your LLM key (OpenAI, Gemini, etc.) with flat, no-seat pricing — designed for small teams. Check it out, if that’s your kind of thing. Programming paradigms are different styles or approaches to writing code, each based on a set of principles and best practices. Choosing the right paradigm can influence how easy your code is to read, maintain, and extend. In this post, we’ll break down three of the most important paradigms: Structured Programming, Functional Programming, and Object-Oriented Programming (OOP). Structured programming emerged in the 1960s and 1970s as a response to the chaos caused by excessive use of goto statements, which often resulted in unmaintainable "spaghetti code."

The Power of Automation: An Introduction to Cron Cron is a powerful utility in Unix-like operating systems that allows you to automate tasks. It's essentially a job scheduler that enables you to run commands or scripts at a specified time or interval. By using cron, system administrators and developers can ensure that routine, repetitive tasks are executed reliably without manual intervention. At the heart of the cron system is the cron daemon (crond), a background service that runs continuously. This daemon reads configuration files called crontabs (short for "cron tables"), which contain a list of commands and their corresponding execution schedules. A crontab entry has two main parts: The Schedule: A series of five asterisks or numerical values that define when the command should run…  ( 7 min )

useState is a native state management hook in React that allows components to keep track of state between renders. Logical Breakdown of useState: Define the initial state: useState(10) → Initializes a number. useState("") → Initializes an empty string. useState(() => "Jack") → Uses a lazy initialization function. Destructure the returned array: useState returns an array with two values: The current state value A function to update the state Example: const [name, setName] = useState(""); Update state using the setter function (setState) Directly modifying the state variable won't trigger a re-render. Always use the setter function to update state: setName("Alice"); // Correct name = "Alice"; // Won't update state Why use setState instead of modifying the variable? For primitive data types (numbers, strings, booleans): Changing the variable only creates a local copy. React won’t recognize the change*.* For reference types (arrays, objects): Modifying the variable directly mutates the original state, which React might not track. Best practice is to spread the existing state and then update it. Updating an Array in State (Best Practice) const [items, setItems] = useState(["Apple", "Banana"]); // Incorrect(Direct mutation) items.push("Orange"); setItems(items); // Correct (Create a new array) setItems([...items, "Orange"]); Updating an Object in State (Best Practice) const [user, setUser] = useState({ name: "Jack", age: 25 }); // Incorrect (Direct mutation) user.name = "Alice"; setUser(user); // Correct (Create a new object) setUser({ ...user, name: "Alice" });  ( 5 min )

Modern applications - from document editors to game engines from UI frameworks to databases - rely heavily on complex, interconnected data models to represent their internal state. These models often form what we call here DOM-like data structures, which in their simplest form can be imagined as a familiar XML or JSON tree. DOM-like data structures are polymorphic, interconnected object graphs characterized by three fundamental layers: 🌲 Tree of Ownership Objects are organized hierarchically, with each parent exclusively owning its children. This structure is acyclic and maps well to serialization formats like XML, JSON, or Protocol Buffers. It forms the backbone of many application data models, enforcing clear ownership boundaries and safe, exclusive containment. 🕸 Web of Weak Referen…  ( 8 min )

OpenAI on Thursday announced GPT-5, a generational upgrade to its large-language models that the company says is “its smartest, fastest, and most useful model yet,” and which is being rolled into ChatGPT, the API and enterprise products. The release packages deeper reasoning, broader multimodal input (text, images, audio and video), and new agentic capabilities that allow models to carry out multi-step tasks on users’ behalf. GPT-5 is presented as a unified system that combines a default, efficient response model with a deeper “thinking” variant and a real-time router that selects the right component for each task. OpenAI describes this as allowing the system to “respond quickly” for routine queries and to spend extra compute—and more sophisticated reasoning—on harder, multi-step problems.…  ( 9 min )

quick intro - Hey, I am a frontend dev trying to level up, and to do that i have decided to daily deep dive into one concept of JS/TS and share what i have learnt so others can engage, cross question and grow. WHY ...REST ? argument object : function showArguments() { console.log(arguments[0]) // 10 console.log(arguments[1]) //20 } showArguments(10, 20); Drawbacks : not a real array so you can't use map,filter,etc other array methods arguments work only on normal functions not on arrow functions store parameters on basis of index and not names hard-to-read code WHAT IS REST ? then why use rest? Rest is real array so you can use all the array methods with it which was not possible with arguments Rest works with arrow functions too unlike 'arguments' rest parameters can be given any naming, improving readability arguments contain only all the parameters passed but rest contains only the extras (other than explicitly defined) example of Rest : function greet(firstName, lastName, ...hobbies) { console.log("First Name:", firstName); // ABC console.log("Last Name:", lastName); // XYZ console.log("Hobbies:", hobbies); // ["Coding","Gaming","reading"] } greet("ABC", "XYZ", "Coding", "Gaming", "Reading");  ( 6 min )

Introduction YAML (YAML Ain’t Markup Language) is a human-readable data serialization language designed for configuration and data interchange. Unlike XML or JSON, YAML uses minimal syntax and indentation (spaces) to represent structure, making it easy for humans to read and write. Developers encounter YAML all the time: it’s the backbone of many DevOps tools (Kubernetes manifests, Docker Compose files, Ansible playbooks, CI/CD pipelines, GitHub Actions workflows, etc.). For instance, GitHub Actions workflows are defined in YAML files (in .github/workflows/), since “YAML is a markup language that’s commonly used for configuration files”. Because of its ubiquity in modern tooling and its focus on readability, understanding YAML is invaluable for developers. YAML’s syntax is defined by a …  ( 11 min )

The future of software development isn't about better prompts. It's about better context. Most AI development starts the same way: a developer opens their coding assistant, types "build me a todo app," and expects magic. Some get lucky with simple projects. Most hit a wall when complexity increases. Whether you're starting a new project or scaling an existing one, the pattern is the same. Initial AI-generated code looks promising, but as requirements evolve and features accumulate, everything falls apart. The AI starts generating inconsistent code. Features conflict with each other. The architecture becomes a patchwork of different patterns. We blame the AI. We blame the prompts. We blame the tools. We're blaming the wrong thing. The problem isn't the AI.

When working on small datasets or low-traffic APIs, LINQ performance rarely becomes a bottleneck. But at enterprise scale, where queries operate on millions of records, every millisecond and allocation matters. The difference between good and great LINQ usage can directly impact throughput, latency, and infrastructure costs. Senior engineers know that optimization isn’t about writing “clever” code — it’s about understanding how LINQ operates under the hood: *Deferred vs. Immediate Execution — * and when to force evaluation. LINQ-to-Objects vs. LINQ-to-Entities — knowing what runs in-memory vs. in the database. Expression Tree Compilation — and how EF Core handles query caching. Memory Allocation Patterns — closures, enumerators, and intermediate collections. Query Translation Costs — minimizing SQL complexity and avoiding N+1 queries. In this section, we’ll focus on techniques that go beyond avoiding .Count() or .ToList() too early. You’ll learn how to profile, measure, and surgically improve LINQ performance in ways that scale for high-load APIs, financial systems, analytics pipelines, and other mission-critical .NET applications. These are battle-tested strategies — the kind used in production environments handling billions of records with sub-10ms query goals. If you’re looking to move from simply “writing LINQ” to mastering LINQ, this is where you start. *For more details..

From securing a local development environment to managing on-call incident response, a common challenge is authenticating with the cloud provider safely and effectively. Instead of using long-lived credentials like secret keys or an overly permissive user account, a more secure practice is to impersonate a service account. This approach allows us to operate with only the necessary permissions, effectively applying the principle of least privilege to our development workflow. In addition to the security benefits, it also minimizes the potential damage from incorrect commands or unintentional actions. This is the same principle for accessing the production environment during on-call rotations, where we should always default to view-only permissions and only escalate to a privileged role when…  ( 11 min )

TL;DR Game Theory dives into the demo for Amanda the Adventurer 3, unpacking the chilling backstory of betrayal and hinting that it might already be too late to rescue our titular heroine. Along the way, MatPat teases every hidden clue from the demo and asks whether anyone can actually save Amanda before it’s game over. They also drop a NordVPN deal, link to the Steam page for the full game, shout out the video’s writing and editing team, and plug Epidemic Sound for royalty-free tunes. Watch on YouTube  ( 5 min )

I really enjoy teaching and explaining things, so I thought I'd give a crack at explaining this idiom in React. Specifically, I am referring to code snippets like the following: const handleClickTab = (title: string): React.MouseEventHandler => (e) => { //Triggered by clicking a tab And then later in the same code: )} What makes this non-straightforward to the untrained eye is the double =>. Yes that's right, we are making a function object/lambda that returns a function! This is because in Typescript or Javascript, functions are first-class values. This means that they can be used like normal expressions. So if we think about a compiler and …  ( 9 min )

Ever walked into a medspa thinking you’d just get your appointment and leave… but instead you’re stuck filling out forms for 20 minutes? Yeah, me too. That’s exactly why I started paying attention to how AI chatbots are changing the game. And trust me, they’re not just some tech gimmick — they can make your whole experience smoother, faster, and, honestly, a lot more personal. A while back, I booked a service at a Medspa in Chicago. I was excited, but the back-and-forth with scheduling, intake questions, and follow-up reminders felt a bit… clunky. Don’t get me wrong, the staff was great — but I kept thinking, “There has to be an easier way.” Enter AI chatbots. And no, not the creepy kind that spam you with ads at 3 a.m., but the smart ones that actually help you. If you’re wondering how …  ( 11 min )

This is a submission for the Redis AI Challenge: Real-Time AI Innovators. I built a real-time, multi‑modal semantic search system that combines vector similarity search with graph‑based context expansion. Text and images are embedded locally using CLIP (openai/clip-vit-base-patch16, 512‑dim). Redis 8 powers the vector index (cosine distance) and fast KNN lookups, and also serves as a cache for query results. On top of the nearest neighbors, I construct and traverse a semantic graph using NetworkX in Python to discover related items beyond the initial top‑K—enabling richer, more explainable retrieval.

Imagine your business has customers all around the world, and you want to welcome each visitor at the closest, fastest front door — no matter where they’re coming from. This is exactly what Anycast Elastic IP (Anycast EIP) does for your cloud applications on Alibaba Cloud. It’s like having a global network of doorways, so users always connect to the nearest one — making your service faster, smoother, and more dependable. What Is Anycast EIP? Anycast EIP takes this a step further by using a technology called Anycast routing. Instead of having just one physical location for that IP address, Anycast lets the same IP address exist at multiple points of presence (PoPs) worldwide. When a user tries to connect, their traffic is automatically routed to the nearest PoP. That means less travel time for data, lower latency, and a better user experience. How Does Anycast EIP Work? This IP is advertised simultaneously from multiple Alibaba Cloud network locations globally. When users access your app, their connection lands on the closest, healthiest PoP automatically. If one PoP goes down, traffic reroutes to the next nearest one without interruption. Why Use Anycast EIP? Easy to Use High Security High Stability and Reliability Low Network Jitter and Latency Real-Life Example: Streaming Service Who Benefits Most from Anycast EIP? Online gaming companies aiming to reduce lag and improve gameplay. Live streaming platforms where smooth video delivery is critical. Financial services requiring secure, low-latency connections. In a Nutshell Anycast EIP is like giving your application many front doors around the world, all with the same address. Visitors are always welcomed at the nearest, fastest door — no matter where they come from — ensuring your service feels local, responsive, and reliable everywhere.  ( 6 min )

Containers are designed to be lightweight, fast, and ephemeral by nature. But what happens when your app needs to retain data between restarts or share files with other containers? That’s where Docker persistence comes in. A container is considered disposed (or removed) when it is explicitly deleted with docker rm, or when it's started with the --rm flag and stops running. In both cases, any data written inside the container that is not stored in a volume will be lost. Your application generates data that must survive container restarts (e.g., database data). You want to share data between containers. You need to back up or migrate container data. Not Persist When: The container is stateless (e.g., an API service, a compute worker).

Today, I learned about SQL (Structured Query Language) and its importance in data analytics. Here’s what I covered today: What is SQL? SQL stands for Structured Query Language. It is used to store, retrieve, update, and manage data in databases. Why we use SQL? To interact with databases easily. To manage large amounts of structured data efficiently. Platforms Used to Run SQL: MySQL Workbench (GUI tool) Command Prompt / Terminal (using MySQL CLI) Online SQL Editors like SQLFiddle, Mode Analytics Database Management Systems like Oracle, PostgreSQL, MS SQL Server What is Big Data? Big Data means extremely large datasets that cannot be handled by traditional data processing tools. Key Components in SQL: Tables Queries Keys (Primary, Foreign) Constraints Joins Rules for Writing Queries: Use proper SQL syntax. Always end queries with a semicolon.

Software Success: Balancing Architecture and Behavior “Your software’s behaviour can win clients today — but only its architecture will keep it alive tomorrow.” What are the two important things a software is expected to do? Well, everyone knows the first one — behaviour — meaning it should behave according to requirements. Easy-pissy. But what is the other important thing? Software architecture — meaning how components of the software are arranged. But is it really important? What if I tell you it has the same value as behaviour, or maybe more, but not less for sure? In this article, my sole purpose is to make you understand the value of architecture in such a way that your hands will get stuck on the keyboard if you do not care about architecture while building software. You, your …  ( 7 min )

Death of the Public Square Punishing good deeds By Osei Harper, MSITM I wanted to talk about something that has long been warned about, for decades — the quiet erosion of fundamental First Amendment protections. Not by corporate robber barons, superPACs, or disingenuous politicians, but by everyday people. Forum moderators, self-appointed ‘post-police,’ and strangers who claim to speak for entire demographics — even when they’re not part of them. Ice-T put it best in his 1989 song “Freedom of Speech”: “Freedom of Speech — Just watch what you say.” I recently wrote some code to fix a problem with ASUS motherboards. I was proud of my work, and I gave it away for free, even though it took weeks to perfect, test, and validate. I left an option open if anyone wanted to show appreci…  ( 9 min )

Many cultures have their rites of passage, often a moment where they have to venture into the world on their own in order to forge their own path. I feel as though I had the privilege of experiencing such a rite, but for me it was the post-apocalyptic internet. I'm 38, ancient by programmer standards and especially for someone who is relatively new to the field. But it also means I was born in a very particular slice of history. As we ushered in the final years of the 1900's, the internet exploded with possibilities. Fortunes were being made overnight, the landscape of commerce was transformed, the dot com reigned supreme, a world wide promise land. Then, as the century closed, we remembered how math works. 1999->2000 Those zeroes were gonna ruin everything! I do remember the panic though…  ( 7 min )

I’ve been building web apps for a while, and lately, I’ve noticed something: Don’t get me wrong : modern tooling is amazing. But sometimes I miss when I could just drop a single .html file, a bit of CSS, and a sprinkle of JS… and call it a day. Now it feels like I need: Node.js (even for a static site) A build pipeline I barely understand Ten npm packages that will all be outdated in 3 months A README that’s longer than the app’s source code So here’s my question: Do you think web dev is genuinely more complex today out of necessity, or have we created our own complexity culture?  ( 5 min )

The task is simple: determine whether a given integer n is a power of two. In other words, return true if there exists some integer x such that: n == 2^x Otherwise, return false. A power of two always has exactly one bit set in its binary representation. For example: 1 = 2^0 → 0b0001 2 = 2^1 → 0b0010 4 = 2^2 → 0b0100 8 = 2^3 → 0b1000 All of these have exactly one bit set to 1. Any number that is not a power of two will either have multiple bits set or will be less than or equal to 0. This leads to an efficient bitwise approach to check whether n is a power of two without using loops or recursion. We use the __builtin_popcount(n) function available in GCC/Clang-based compilers. This function returns the number of set bits (bits equal to 1) in the binary representation of n. A power of two has exactly one set bit, so we check if __builtin_popcount(n) == 1. We also ensure n > 0, since negative numbers and zero cannot be powers of two. class Solution { public: bool isPowerOfTwo(int n) { return n > 0 && __builtin_popcount(n) == 1; } }; JavaScript does not have a built-in popcount function, but we can convert the number to binary and count the number of 1s: var isPowerOfTwo = function(n) { return n > 0 && n.toString(2).split('1').length - 1 === 1; }; Alternatively, use a bitwise trick: var isPowerOfTwo = function(n) { return n > 0 && (n & (n - 1)) === 0; }; Python also lacks a direct popcount, but we can use the bin() function: class Solution: def isPowerOfTwo(self, n: int) -> bool: return n > 0 and bin(n).count('1') == 1 Or using the bitwise trick: class Solution: def isPowerOfTwo(self, n: int) -> bool: return n > 0 and (n & (n - 1)) == 0 Time Complexity: O(1) Space Complexity: O(1) Final Thoughts This is a straightforward bit manipulation problem. The use of __builtin_popcount or (n & (n - 1)) == 0 makes the check both efficient and concise. Knowing how powers of two behave in binary is the key insight here.  ( 7 min )

Beyond Sight- Unitree A2 Quadruped Sees the World in 3D The world of quadruped robotics just took a significant leap forward. Unitree, a company quickly making a name for itself in the legged robot space, has officially unveiled its new A2 model. While it boasts impressive improvements in speed and agility, the real headline is its revolutionary approach to navigation. The A2 is equipped with both front and rear-facing 3D lidar sensors, giving it a near-complete spherical understanding of its environment and setting a new standard for autonomous mobility in its class. This dual-lidar system is a game-changer. Unlike robots that rely solely on cameras or a single forward-facing sensor, the A2's setup provides a comprehensive, 360-degree by 90-degree hemispherical field of view with an almost non-existent blind spot. This allows the robot to not only see what's ahead but also to perceive obstacles and terrain changes beside and behind it. This constant, rich point-cloud data enables the A2 to navigate incredibly complex, uneven, and dynamic environments with unprecedented confidence. It can avoid moving objects, traverse stairs, and handle rough ground with a level of fluid intelligence that was previously the domain of much more expensive research platforms. The implications of this technological advancement are profound. By integrating such a sophisticated perception system into a commercially available robot, Unitree is challenging established players and dramatically lowering the barrier to entry for advanced robotics applications. The A2 is poised to excel in roles like industrial inspection, remote surveying, security patrols, and academic research. Its enhanced terrain-handling capabilities make it a more reliable and versatile tool, pushing the industry closer to a future where autonomous quadrupeds are not just a novelty, but a common and indispensable part of our technological landscape.  ( 8 min )

Generative AI tools like ChatGPT, Claude, and Gemini are no longer futuristic experiments. We use them to: Write code in seconds Draft blog posts and marketing copy Summarize research papers Even explain complex topics in plain English The productivity boost is undeniable. The Rise of AI Dependency Calculators were said to destroy mental math Google Search was blamed for reducing memory retention Spell checkers made us forget tricky words Now with Generative AI, it’s not just facts or formulas, it’s thinking and reasoning that are on the outsourcing table. Why wrestle with a bug when AI can hand you the solution instantly? This AI dependency feels efficient until we realize we’ve skipped the mental workout. The Real Danger: Cognitive Atrophy Reduced problem-solving stamina Loss of creative “struggle time” where innovation sparks Over-reliance on external assistance for basic thinking tasks This isn’t laziness in the Netflix-binge sense it’s mental outsourcing disguised as productivity. Generative AI: Bicycle or Wheelchair for the Mind? The difference lies in how we use it: Ask “why” and “how”, not just “what” Use AI as a co-pilot, not an autopilot Alternate between AI-assisted and manual problem-solving Use AI to learn faster not skip the learning entirely A Simple Self-Check “Am I avoiding this task because I’m exhausted or because I don’t want to think through the hard part ?” If it’s the first, take a break. That’s how you keep your brain in shape while still leveraging AI’s power. The Future Belongs to Thinkers Who Use AI Wisely The future will belong to those who: Use AI for speed Keep their independent reasoning skills sharp Stay curious and willing to solve problems without automation Because when everyone has access to the same AI tools, your brain becomes your ultimate competitive edge. 💬 What’s your take is Generative AI helping us think better, or making us mentally weaker?

How to Copy a View Only Google Doc—ever been stuck with a file you could only view and wondered, Can You Copy A View Only Google Doc? If you want to Copy Text From View Only Google Doc without hassles, this post walks you through easy methods to do just that. When someone shares a Google Doc as “view only,” it means they don’t want others changing it—or sometimes even copying it. It’s a way to keep control over who edits or redistributes the content. But what if you just need a copy for your own notes or reference? That’s where the question, Can You Copy A View Only Google Doc comes in. Try this quick trick: Open the Google Doc. In the URL, find the part that says "edit" and replace with "mobilebasic". Press Enter. The page reloads in a simpler format where you can highlight and copy the text easily. If the first trick doesn’t work: Open Developer Tools (Ctrl+Shift+I on Windows or Cmd+Opt+I on Mac). Find the setting to disable JavaScript temporarily. Refresh the page with JavaScript off. You should now be able to select and copy the text. Google Docs often lets you make your own copy if the owner permits: Click File > Make a copy. Save it to your Drive. If this option is missing, it’s because the owner disabled copying explicitly. If you want to share documents without others being able to copy: Share as View Only. In sharing settings, disable “Viewers and commenters can see the option to download, print, and copy.” Avoid sharing mobile links that bypass restrictions. How to Copy a View Only Google Doc is about understanding where Google puts limits—and how to work around them responsibly. Still asking yourself, Can You Copy A View Only Google Doc? Yes, it’s possible, but keep in mind why those restrictions are in place. Use these steps to Copy Text From View Only Google Doc thoughtfully and ethically. That way, you avoid trouble and get the content you need. Watch The Full Guide Here.  ( 6 min )

There are moments when you want Ansible to stop printing anything own and just to show output of the remote command. Like ssh user@server command, but with all Ansible bells and whistles, with custom ssh arguments, transports, etc, etc. I'm talking about the ansibile binary, not the ansible-playbook, although, with some tinkering, it's possible to use this trick with ansible-playbook too. Foundation for tricks: Use raw module (disaANSIBLE_LOAD_CALLBACK_PLUGINS=1 ANSIBLE_STDOUT_CALLBACK=json ansible -i localhost, -m raw -a 'cat /etc/passwd' all -c local | jq -r '.plays[].tasks[].hosts | to_entries[] | "(.key):\n(.value.stdout)\n"'bles AnsiballZ mechanism) Use json output (which allow to extract stdout without using unsound grep expressions). Process it with jq. Ask jq not to print quotes for string value. Here it is: ANSIBLE_LOAD_CALLBACK_PLUGINS=1 \ ANSIBLE_STDOUT_CALLBACK=json \ ansible -i localhost, -m raw -a 'cat /etc/passwd' all -c local \ | jq -r '.plays[].tasks[].hosts[]?.stdout' Disection: Env variables says ansible to load callback plugins and to use json callback plugin (output). -i localhost, and -c local are not important. Use a proper inventory here if you need. localhost here just for an example. -m raw -a command is usual ansible invocation -r for jq removes quotes from a string. Expression .plays[].tasks[].hosts[]?.stdout scans all hosts in all tasks for all plays and prints stdout. Why do you need it? Well, the thing I wanted to do was to get a secret file from a remote server and encrypt it locally on the host using sops. I can use community.sops.sops_encrypt module, but it require multiple steps to do, and secrets are nasty to debug, so I don't want to do those steps. A 'simple' ansible call with | sops -e is require less attention. But, it requires this 'pristine output' from ansible to avoid mangling the content, so, I had to invent this quirk.  ( 6 min )

⚜️SUID, SGID, and the Sticky Bit are special permissions in Linux and other Unix-like operating systems that modify how files and directories behave. They are used to enhance system security and manage access control more effectively. 💡SUID (Set User ID): 👉Why it's Used SUID is crucial for programs that need to perform tasks requiring elevated privileges, but are run by ordinary users. A classic example is the passwd command. When a user changes their password, the passwd program needs to write to the /etc/shadowfile, which only the root user can modify. By setting the SUID bit on the passwd executable, a regular user can run the program, and it will temporarily execute with root privileges, allowing it to write to the secure file. 👉How to Identify and Set: If the 🔑owner's execute bit …  ( 7 min )

Memory in C# (and .NET Core) is divided into two key regions: Stack and Heap. Both are essential for memory management, but they serve different purposes and behave differently. Understanding how they work helps you write faster and more reliable applications. The Stack is a memory region used to store: Value types (int, bool, struct, etc.) Local variables Method call data (like parameters and return addresses) It's called a "stack" because it works like a stack of plates - the last item pushed is the first one popped. Once a method ends, all its stack-allocated memory is cleaned up automatically.

Keyword lists are like restaurant order forms where each field has a clear label and you can repeat certain items when it makes sense. Unlike a table setting where each position holds one specific item, an order form lets you write "drink: water, appetizer: salad, drink: soda" - keeping everything in order and allowing duplicates when needed. Think of [timeout: 5000, retry: 3, retry: 5] as a configuration form where some options can be specified multiple times, each with its own meaning and context. While this flexibility makes keyword lists perfect for function options and small configurations, it also makes them quite different from maps in both behavior and use cases.

After completing Codecademy’s Beginner Python 3 course, I took a couple of weeks to explore a different platform, introduce some variety into my learning, and continue building my skills. That short break gave me a fresh perspective, and now I am ready to dive back in with renewed energy. This time, I am taking on something much bigger: Codecademy’s Backend Engineer Career Path. Over the course of my Python journey so far, I have realized something important. This will be no surprise if you have read any of my other posts, but I am far more drawn to backend development than frontend. I love the logic, the structure, and the problem-solving that happens behind the scenes. This next step feels like the natural direction for me. I want to be transparent throughout this process, sharing my wins, my challenges, and the lessons I pick up along the way. I would love for you to join me on this journey (this is a way to hold myself accountable and keep me on track). Whether you are learning alongside me, a step ahead, or a seasoned mentor, your insights, encouragement, and feedback will be invaluable. If you are on a similar path, let’s connect. I am always excited to build relationships with others who share the same passion, whether we are at the starting line together or you have been running the race for years.

When working with WebSockets in NestJS using gateways, developers quickly encounter a fundamental challenge: traditional authentication guards don't work seamlessly with JWT tokens, especially short-lived ones. Unlike HTTP requests where each call can be independently authenticated, WebSocket connections are persistent, creating unique authentication requirements. NestJS guards are designed for request-response cycles, but WebSockets maintain long-lived connections. If you're using short-lived JWT tokens and attempt to verify authentication on each message, the token will eventually expire mid-connection, breaking the user experience. This leaves developers with a few viable approaches. The most straightforward approach is using session-based authentication, where guards can function norma…  ( 7 min )

For most of my professional life, I worked in business development, sales, healthcare, and social care — providing support, safeguarding, and ensuring the well-being of vulnerable individuals. It was meaningful work, but deep down, I had another passion: technology and cloud computing. In 2023, I decided to take a leap into the AWS Cloud world as a Solutions Architect. I earned the AWS Certified Cloud Practitioner and am currently working toward the AWS Cloud Solutions Architect certification. I started mentoring students through AWS Academy — first with e-Careers, and now with OptimaIT — to gain more hands-on experience and become better equipped to solve real-world cloud use cases. The journey wasn’t always smooth — here’s what I learned along the way. Skills Transfer More Than You Think…  ( 7 min )

👉The sudo (superuser do) command is a crucial tool in Unix-like operating systems that allows a permitted user to execute a command as another user, typically the superuser (root). 💡Why sudo is Used: Using sudo is a security best practice. Instead of sharing the root password or having multiple users logged in as root, sudo grants specific users temporary, command-specific privileges. This reduces the risk of accidental system damage or malicious activity, as it limits the scope of a user's elevated permissions. Additionally, sudo logs all commands executed, providing an audit trail. sudo Syntax and Basic Usage sudo [options] command For example, to update a package list on a Debian-based system, you would run: sudo apt update 👉When you first use sudo in a session, you'll be prompted …  ( 7 min )

The Day My Flutter IDE Went Silent One day I was working on a Flutter project then I noticed something was off. That helpful suggestion to add const to my widgets? Gone. The quick fixes that used to automatically optimize my code? Completely vanished. Something was definitely wrong, and I needed to figure out what happened to one of Flutter's most important performance optimization features. After trying various fixes, I discovered that the most reliable and permanent solution wasn't restarting servers or reinstalling extensions. It was something much simpler: properly configuring my analysis_options.yaml file. The issue isn't actually with your IDE or the Dart analysis server most of the time. It's about lint rules configuration. The const suggestions you're missing are powered by speci…  ( 7 min )

What developers can learn from one of 2025's biggest privacy fails Meta just handed every developer a textbook example of how NOT to build privacy-respecting features. Instagram's new Friend Map launched this week with promises of user control and opt-in location sharing. Within 48 hours, it became a cautionary tale that'll be discussed in engineering ethics classes for years. Here's what happened, why it matters for developers, and what we can learn from Meta's mistakes. Instagram's Friend Map was supposed to be simple: an opt-in feature that lets you share your "last active location" with friends. Think Snapchat's Snap Map, but for Instagram's 2 billion users. The marketing was clear: "location sharing is off unless you opt in." Sounds privacy-friendly, right? But users quickly discovere…  ( 8 min )

Or: How I accidentally stumbled onto the next fundamental protocol layer I’m not a developer — I’ve spent my career in tech support, watching production systems break in the real world. But over the past month, I’ve stumbled onto an idea that I think exposes a massive infrastructure gap we’re all going to feel soon. It started innocuously enough. Like many of you, I was frustrated watching AI demos that worked perfectly in controlled environments fall apart the moment they tried to interact with real websites and APIs in production.

Raw thoughts from the trenches of building better retrieval systems You know that feeling when your RAG system returns technically correct but completely useless chunks? Yeah, I was there. My traditional text splitters were butchering documents like a blunt knife through steak - creating arbitrary 512-token chunks that split sentences mid-thought, separated context from conclusions, and generally made my retrieval system feel like it had amnesia. I was getting chunks like this: Chunk 1: "...the economic impact was severe. Inflation rose to" Chunk 2: "15% by the end of the quarter, causing widespread" Chunk 3: "concern among investors and policymakers who..." Useless. Absolutely useless.

Conclusion By following these best practices, teams can harness the power of Agile methodologies to deliver high-quality software efficiently and adapt to the dynamic nature of modern development projects.  ( 6 min )

This is part 3 of a series on developing Wear OS apps with Flutter. part 1 for an introduction to Wear OS and common design guidelines and part 2 to setup and install your first Wear OS app! Wear OS support in existing Flutter packages is limited. For example, if you want to get the device's location, the most common ways tend to be to install a package like locationor geolocator. However, both of these currently have known issues or incompatibilities with Wear OS. It's still very easy to implement our own native code that can be called from Flutter, using Platform Channels. With Flutter, it's always easy to rely on these abstractions that are provided for us, but Platform Channels are very useful to understand, because they are actually how all the packages we use are implemented under-th…  ( 9 min )

A new OS Switch A new OS Switch felt like a career switch. Switching to linux felt weird and new to something interesting because of using Windows for the past three years but it gave me a new experience of switching to linux. What is Linux Linux is a free, open-source operating system (OS) that operates in a computer. It was created in 1991 by Linus Torvalds and is based on the Unix operating system principles. Features of Linux OS Open-Source – Anyone can view, modify, and distribute the source code. Secure – Strong user permissions and community updates make it less vulnerable to viruses. Customizable – Change almost anything: desktop layout, themes, functionality. 4.Stable and Reliable – Rarely crashes, making it popular for servers. 5.Free to Use – Most Linux distributions cost nothing. How to install Linux OS Download a Linux ISO Go to your chosen distribution’s official website (e.g., Ubuntu, Linux Mint) and download the ISO file. For beginners, Ubuntu or Linux Mint is recommended. Create a Bootable USB Use a tool like Rufus (Windows) or Balena Etcher (Mac/Linux) to write the ISO file to a USB drive (8GB or larger). Boot from USB Restart your PC and enter the boot menu (press F2, F12, Esc, or Del at startup). Select your USB drive to load Linux. the keys vary depending on the particular laptop or PC models 4.Install Linux Select Install Choose your language and keyboard layout Pick installation type (dual-boot or erase disk) Create a username and password Click Install and wait for it to finish Post Installation Setup After reboot Update your system bash sudo apt update && sudo apt upgrade Conclusion By now, you’ve successfully installed Linux on your machine and taken your first step into the open-source world. Whether you’re using it for coding, server management, or everyday tasks, Linux offers speed, security, and flexibility that few other operating systems can match. Happy Linux-ing techies !  ( 6 min )

As JavaScript developers, we all know the notorious pain of the node_modules folder - it's become a gargantuan entity of its own. You clone a simple project, run npm install, and suddenly hundreds of megabytes are consumed. The irony? Most of these files are unnecessary bloat - tests, documentation, and configuration files that never see the light of production. Even with modern package managers like pnpm and Bun, while the situation has marginally improved compared to npm CLI, the fundamental problem persists. Today, I'm excited to introduce prune-mod - a tool I developed to tackle this exact problem. Despite being an ultra-lightweight 8.3KB tool, prune-mod can reduce your node_modules size by up to 60% without compromising your application's functionality. Key features that set this tool apart: • Intelligent runtime detection: Automatically leverages Bun if available, boosting processing speed by up to 3x Dry-run mode for previewing changes before applying them Safety-first approach: Never removes critical files like package.json entry points Seamless CI/CD and Docker integration for optimizing image sizes Usage couldn't be simpler: npx @usex/prune-mod This tool particularly shines in these scenarios: • Serverless deployments with strict size limitations (I personally faced this challenge on Cloudflare) Docker containers where you need faster uploads and pull times Local development when you need to reclaim precious disk space Real-world impact: On a typical Next.js project, we've seen reductions from 487MB to 193MB - that's 60% smaller with 44% fewer files! The project is open source, and I welcome contributions, feedback, and suggestions from the community. GitHub: https://github.com/ali-master/prune-mod NPM: https://www.npmjs.com/package/@usex/prune-mod I hope this tool proves as valuable to you as it has been for me, reducing daily development friction and accelerating your deployment cycles after every git push. Let's make our codebases leaner and our deployments faster together!  ( 6 min )

For any business that want to rank in “near me” search results, creating well-optimized location pages is essential. Whether you're a single-location or multi-location brand, these pages help you speak directly to local searchers—and search engines. Avoid duplicate content across pages. Tailor each page to its respective city or neighborhood by including local landmarks, service differentiation, and client stories to build trust and authenticity. Include name, address, and phone number (NAP) with consistent formatting across every page—for both user clarity and search engine trust. Incorporate geo-focused keywords (e.g., "SEO Consultant in Dubai Marina") into titles, meta descriptions, headings, and alt-text to boost relevance. Embed Google Maps and include relevant LocalBusiness schema. This not only enhances user experience but also aids rich snippet generation. Add localized reviews, staff profiles, and testimonials to boost credibility and differentiate each location page. Use consistent URL slugs (e.g., /dubai-marina-seo) and interlink location pages naturally from your homepage or service overview. This helps search engines and users navigate your local footprint better. Here's How to Optimize Location-Specific Pages for Local SEO Success 1. Higher rankings: Location pages signal to Google your relevance for local intent including map pack placements. 2. Better user engagement: Location-specific, actionable info improves session duration and conversion rates. 3. Scalable approach: A templated but customizable structure allows rapid rollout across multiple geographies. Also Read, SEO Myth-Busting: Keyword Stuffing & Meta Keywords Are Dead Location pages are your strongest tool in the local SEO toolkit. When optimized thoughtfully—with unique content, structured data, local credibility, and clear navigation—they drive foot traffic, conversions, and visibility in local search.

Though smart contracts have powerful features, they have a fatal flaw: they can only access on-chain data and cannot fetch off-chain data. For example, a smart contract cannot know today’s weather, the stock price, or the result of a competition. Therefore, we need an oracle. An oracle is a type of middleware that securely feeds off-chain data to smart contracts. Request initiation – The smart contract emits an event requesting specific off-chain data (e.g., a random number). Data retrieval – Oracle nodes listen for these requests and fetch the required data from external sources, such as APIs or IoT devices. Verification and aggregation – Multiple independent oracle nodes provide the same type of data. The network compares the responses, filters out anomalies, and aggregates results to reach consensus. On-chain submission – The verified data is packaged into a blockchain transaction and sent back to the requesting smart contract. Example: Chainlink Currently, Chainlink is the most famous decentralized oracle network. It uses an economic incentive mechanism: rewarding honest nodes and penalizing malicious ones, thereby ensuring data security. In summary, an oracle solves the problem of smart contracts being unable to fetch off-chain data, and serves as a critical bridge connecting blockchain and the real world. ps: some people think oracle is like magic, but it’s really just well-designed data plumbing.  ( 5 min )

When I first started working with Go’s concurrency model, channels seemed mysterious. I knew they were a way for goroutines to talk to each other, but the finer points of how they communicate and when to close them were still fuzzy. After experimenting with a simple example, I now have a much clearer mental model. 1. Channels Are Pipelines for Communication A channel in Go is like a conveyor belt between goroutines. A sender puts values onto the belt. A receiver takes values off the belt. You can think of it as: ch := make(chan int) // a channel for int values Now ch is ready to carry int data from one goroutine to another. 2. Sender Channels vs Receiver Channels In Go, you can explicitly mark a function’s parameter as a send-only or receive-only channel: chan<- int → send-only channe…  ( 6 min )

From WordPress to Node.js When we first started building food delivery websites, we relied on tried-and-true tools — WordPress and WooCommerce. Technologies like PHP were no longer inspiring — we wanted something modern, modular, and flexible.

At the time, we chose Sails.js as the framework — it was simple and easy to understand, allowing us to quickly build an MVP. Yes, it’s aging now and we’re considering migrating to a newer stack, but back then it was the optimal choice.

Mastering State Management with Zustand in Modern React Applications State management is at the heart of every React application. As your application grows in complexity, managing various pieces of state across components becomes increasingly challenging. While libraries like Redux have long been the go-to solution, they often bring a lot of boilerplate and complexity. Enter Zustand — a minimal, unopinionated, and powerful state management library that offers simplicity while satisfying the needs of modern applications. In this blog post, we’ll dive deep into Zustand, explore how it compares to other state management solutions, and build a small yet functional React project using Zustand. Zustand (German for "state") is a small, fast, and scalable state-management solution created by the…  ( 8 min )

Why I Even Started This A few months ago, I was working on a personal web project and hit a problem: Some of my images were just too low-res. Sure, I could open Photoshop, run some filters, and try to clean things up… but it took forever, and the results were hit-or-miss. That made me wonder: "Could I build something that fixes this in seconds using AI?" I wanted a simple, browser-based tool that could: Upscale small or blurry images without making them look weird Transform or restyle visuals (different color moods, art vibes) Generate new graphics from a text prompt when I needed something fresh Basically, a fast, no-friction image enhancer for devs, designers, and creators. I used a mix of modern AI models for super-resolution, style transfer, and text-to-image generation. The frontend is plain HTML/CSS/JS for speed, and the backend handles the AI processing in the cloud. What I learned: AI upscaling isn’t just “make bigger” — it’s about hallucinating realistic detail Some styles work better on certain image types (portraits vs UI screenshots) Keeping UX minimal is key — most people just want to drag, drop, done Try the Demo If you’re curious, I put up a free demo while I’m still collecting feedback. No account needed, works in your browser: 🔗 Demo link here It’s early-stage, so expect rough edges. If you break it, I want to hear about it. I know a lot of DEV folks work on side projects, blogs, or portfolios. If you’ve got low-res screenshots or want to experiment with image styles, this might save you some time. Also, if you’ve built something similar or played with AI upscaling before, I’d love to compare notes. P.S. Mods — This post is about sharing the build process & lessons learned, not just a promo. If anything here feels off for the rules, I’m happy to edit.  ( 6 min )

After Phase 4.1 showed that AI shouldn't handle mechanical project setup, I moved to something more promising: Can AI help translate business requirements into actionable development work? This experiment tested whether AI could serve as an intelligent business analyst, breaking down technical specifications into user stories and then into specific development tasks with test criteria. The results revealed important patterns about AI collaboration and led to a breakthrough in prompt organization that I've been applying across all VibeTDD work.

We are all excited about the potential of Generative AI (GenAI) to boost our productivity. However, it's crucial to critically evaluate where and how we apply these tools, especially in areas like software testing. This post explores why relying solely on GenAI to generate unit tests can be an anti-pattern, ultimately undermining the very purpose of testing. Unit tests are about verifying that the code we write aligns with our intended design and discover bugs as early as possible. They force us, as developers, to clearly articulate the behavior we expect from a specific unit of code. To focus purely on the implementation details, we strategically mock dependencies. This isolation allows us to confidently assess if the code behaves as we designed it—a critical part of the development proce…  ( 7 min )

A year ago, I was quietly experimenting with AI tools—fine-tuning small models, automating workflows, and reading everything I could about machine learning. But here’s the truth: nobody knew.

This is a submission for the Redis AI Challenge: Beyond the Cache. A real-time air traffic control simulator that can track aircraft positions (latitude, longitude, altitude). Detect potential collisions using geospatial calculations, and visualize aircraft movement on a live map. It also generates alerts when aircraft violate safety thresholds. Here is the GitHub repo: https://github.com/SebastianKibiriti/redis-airtraffic-simulator-with-deepseek The features of Redis 8 that were used are: GEOADD, for storing the positions of the aircraft + GEORADIUS, for querying other aircrafts nearby. # Store aircraft positions redis.geoadd( "aircraft:positions", {aircraft_id: (longitude, latitude)} ) # Query nearby aircraft (1km radius) conflicts = redis.georadius( "aircraft:positions", current_lng, current_lat, 1, "km" ) Lua Scripting for collision detection. -- conflict_check.lua local nearby = redis.call('GEORADIUS', KEYS[1], ARGV[1], ARGV[2], 1, 'km') -- Checks altitude differences using ZSCORE Streams, for real-time alerts. little to no alerts will be missed with faster replication. # Trigger alert redis.xadd( "conflict_alerts", {"trigger_id": "flight123", "conflicts": "flight456"} ) # Frontend consumes via WebSocket alerts = redis.xread({"conflict_alerts": "$"}, block=0) Multithreaded I/O to optimize performance. This allows for more that 1000+ concurrent aircraft updates to be handled. The combination of geospatial, streaming, and Lua scripting creates a unique traffic management system.  ( 5 min )

OpenAI’s GPT-5 livestream was an hour long, packed with demos and model comparisons. But somewhere around the 44-minute mark, three updates were mentioned so casually you could have blinked and missed them. If you’re building Agents, though, these are not small tweaks — they’re weapons-grade upgrades. They hit the exact pain points that slow us down: tool calls that feel like black boxes, payloads broken by escape-sequence chaos, and output formats that never quite stay in line. Here’s why these “80 seconds of airtime” might be the most important thing in GPT-5 for agent developers. In OpenAI’s 1-hour GPT-5 livestream, there’s an 80-second stretch (44:10–45:30) where Michelle Pokrass drops three new features so casually you could blink and miss them.

The internet loves good vibe coding post like "AI wrote my app in 5 minutes". I mean, attention is gold in content creation and I totally get it but it doesn't show the other side of the process. Especially about the part where people say its replacing developers. It does raise the bar as now anyone can build a product with LLMs and vibe coding is fast. It feels smart. But it's not replacing developers. It's reminding us why they still matter. Vibe coding is what happens when developers offload code generation to AI. You give a high-level instruction like: "Write a function to parse a config and return only the active keys." and let the AI do the rest. The appeal is real. You get speed, fewer keystrokes, and less context-switching. The code often looks right, but that's not the same as bei…  ( 8 min )

When building modern web applications, performance isn't a luxury — it's a necessity. Next.js comes with built-in code splitting to help you deliver faster, leaner apps by loading only what’s needed.

If you’ve ever worked with web development, APIs, or security tokens, chances are you’ve bumped into Base64 encoding — maybe without even realizing it. For many developers, Base64 is just that weird output when you “convert an image to text.” But in reality, it’s a powerful and practical tool for solving everyday problems in software development. This makes it safe to send binary files (like images, PDFs, or ZIP archives) over channels that only support text — such as JSON, XML, or email. Hello → SGVsbG8= When I Use Base64 in Real Life Sending files in JSON APIs JWT token debugging Storing binary inside config files The Downsides You Should Know It’s not encryption — don’t treat it as a security feature. Large files might cause performance issues if handled entirely as Base64. Base64 Examples in Different Languages // Encode const text = "Hello World"; const encoded = btoa(text); console.log(encoded); // SGVsbG8gV29ybGQ= // Decode const decoded = atob(encoded); console.log(decoded); // Hello World Python import base64 # Encode text = "Hello World" encoded = base64.b64encode(text.encode()).decode() print(encoded) # SGVsbG8gV29ybGQ= # Decode decoded = base64.b64decode(encoded).decode() print(decoded) # Hello World PHP My Favorite Tool for Base64 It’s: 100% client-side (your data stays in your browser). Works with both text ↔ Base64 and file ↔ Base64. Has a clean, mobile-friendly UI. Final Thoughts Next time you need to transfer binary data through a text-only channel, think Base64 — and save yourself a few headaches.  ( 6 min )

When people talk about performance, they usually think about Lighthouse scores, lazy loading, or caching. But there’s something deeper under the hood — the Critical Rendering Path (CRP) — the sequence of steps the browser takes to turn your HTML, CSS, and JS into pixels on the screen. If you understand and optimize it, your site feels instant. What is the Critical Rendering Path? It’s the browser’s “checklist” for rendering: 1️⃣ HTML → Parse & build DOM CSS → Parse & build CSSOM JavaScript → Execute and potentially block rendering Render Tree → Merge DOM + CSSOM Layout → Calculate positions & sizes Paint → Fill pixels on screen Any delays in these steps = slower First Contentful Paint (FCP) & Largest Contentful Paint (LCP). CRP Optimization Techniques 1. Inline Critical CSS Load only the styles needed for above-the-fold content in the . header { background: white; } /* ...critical styles here... */ Then load the rest asynchronously. 2. Defer Non-Critical JavaScript Use defer or async to prevent JS from blocking rendering. 3. Minimize Render-Blocking Resources Combine small CSS files Serve minified assets Use preload for fonts & hero images 4. Use next/script Strategically (Next.js) Prioritize scripts that affect above-the-fold UX. import Script from "next/script"; 5. Reduce Critical Path Length Limit DOM depth Reduce unnecessary CSS selectors Avoid oversized images 6. Measure & Monitor Use: Chrome DevTools → Performance tab Lighthouse → Opportunities WebPageTest → Filmstrip view Why It Matters A fast CRP = Performance is not just about scoring 100 — it’s about making the first interaction feel instant.

When you first encounter the Readonly keyword in C#, it seems straightforward, prevent fields from being reassigned after construction. But once you start applying it to reference types, things get more nuanced. value vs. reference types, and what developers should keep in mind to write safer, cleaner code. In C#, the Readonly keyword: Can be applied to fields. Ensures the field can only be assigned during declaration or inside the constructor of the class/struct. Once assigned, the field can't point to a different object. public class User { public string Name { get; set; } } public class Account { private readonly User _user = new User(); public void ChangeUser() { // This is possible _user.Name = "New Name"; // But this will result in compile-time error _user = new User(); } } Misunderstanding: reference type doesn't make the object itself immutable, it only means the reference can't be reassigned. You can still modify the object's internal state. Value Types: readonly int number = 5; // Compile-time error number = 10; With value types (like int, bool, struct), Readonly means you cannot change the value. Reference Types: readonly List items = new List(); // Possible items.Add("Test"); // Compile-time error items = new List(); So, the object can still mutate , it's the reference that's locked. To make an object's state immutable, you must: Avoid set accessors in properties. Make all fields Readonly. Use init accessors for initialization only. Don't expose collection fields directly. *Example public class User { public string Name { get; init; } } Radonly with Properties public string Role { get; init; } = "admin"; These make the property immutable after initialization.  ( 6 min )

In real-world Laravel applications, it’s common to work with complex data structures. Sometimes, we have a nested attribute like details.name in our model, but in other cases, the same data might exist at the root level, e.g. name. If you always use data_get($model, 'details.name'), you risk getting null when the nested attribute is empty — even if the root attribute exists. This can happen when working with data that comes from different sources or has different states (e.g., draft vs. submitted applications). Here’s a common scenario: return [ 'name' => data_get($company, 'details.name'), 'category' => data_get($company, 'details.category'), 'authorised_capital' => data_get($company, 'details.authorised_capital'), ]; If details exists but details.category is empty, Laravel’…  ( 8 min )

🔹 Problem: Power of Two Difficulty: #Easy Tags: #Math #BitManipulation Given an integer n, determine if it is a power of two. A number is a power of two if it can be written as 2^k for some integer k ≥ 0. True if n is a power of two, otherwise return False. Brute Force Idea: Keep dividing n by 2 while it’s even. If we ever hit an odd number before n becomes 1, it’s not a power of two. If we reach 1 exactly, it is a power of two. This works because a power of two in binary has exactly one 1 bit. Optimized Strategy: Use bitwise trick: n > 0 and (n & (n - 1)) == 0 This works because powers of two have exactly one bit set, so subtracting 1 flips that bit and sets all bits after it to 1. AND-ing them results in 0. But here, I implemented the division approach, which is still O(log n) and easy to understand. Algorithm Used: Simple iterative division check. ⚙️ Code Implementation (Python) class Solution: def isPowerOfTwo(self, n: int) -> bool: while n != 1: if n % 2 == 1 or n == 0: return False n //= 2 return True Time: O(log n) — Each step halves n. Space: O(1) — No extra memory used. ✅ Powers of two in binary have only one bit set. 💡 Division method is beginner-friendly, bitwise method is constant-time. 💭 If a problem involves checking for power of two, consider both math and bit tricks.

I've been an SRE engineer for over two years now. SRE stands for Site Reliability Engineering. It's about keeping production systems reliable and efficient. But here's the thing - it's not just about learning fancy terms. You know, SLA, SLO, MTTR, service reliability. That stuff matters, but the real work is keeping systems stable and making processes better. Since college, I believed one thing: skills beat paper. I thought you didn't need good grades or certifications. Just be good at what you do. That's it. Spoiler alert: I was completely wrong. Back then, I was all about side projects. I'd spin up my own VMs. Set up Caddy servers. Configure Cloudflare. Build stuff that actually worked. This felt real. This felt valuable. Why would I need a piece of paper when I could show actual results…  ( 8 min )

In Java, throw is a keyword used to explicitly throw an exception. Here's a breakdown of the what, why, how, and when to use it: What is throw in Java? throw is used to manually trigger an exception during program execution. It transfers control from the current block of code to the nearest catch block that can handle the exception. throw new IllegalArgumentException("Invalid input"); Why use throw? You use throw to: Handle unexpected situations or errors in your code. Validate input (e.g., null values, invalid arguments). Provide custom error messages or throw custom exceptions. Improve code robustness by catching problems early. How to use throw in Java? ✅ Syntax: throw new ExceptionType("Error message"); public void setAge(int age) { if (age < 0) { throw new IllegalArgumentException("Age cannot be negative"); } this.age = age; } Note: The object thrown must be of type Throwable (i.e., Exception or subclass). class MyException extends Exception { public MyException(String message) { super(message); } } public void checkSomething(boolean condition) throws MyException { if (!condition) { throw new MyException("Condition failed"); } } When to use throw in Java? Use throw when: You need to stop normal flow due to a problem. Input is invalid or violates rules. Something unexpected happens (e.g., file not found, null value). You are implementing custom business logic exceptions. Forgetting new when creating the exception: throw IllegalArgumentException("error"); // ❌ wrong throw new IllegalArgumentException("error"); // ✅ correct Throwing a non-Throwable type: throw "error"; // ❌ wrong Forgetting to declare or handle checked exceptions: public void riskyMethod() throws IOException { throw new IOException("Disk not found"); // must declare or handle } Would you like an explanation of the difference between throw and throws too?  ( 6 min )

Like the title says, this article is going to be about an alternative mental model to learning about and possibly teaching data structures and algorithms. The reason I'm writing it is out of a personal gripe of mine, so allow me to tell you a bit about myself first. If you want to skip that though, you can go sthreat to “The Mental Model”. Like many developers in today's landscape, I did not go through a formal education in computer science. I went to college for management information systems for a few years, barely did any math and/or theoretical programming classes, and was thrust into the world of systems administration. After about 2 years of that, I got laid off and decided instead of looking for another job in that field, I'd focus on trying to do what I always wanted to do - code f…  ( 14 min )

231. Power of Two Difficulty: Easy Topics: Math, Bit Manipulation, Recursion Given an integer n, return true if it is a power of two. Otherwise, return false. An integer n is a power of two, if there exists an integer x such that n == 2x. Example 1: Input: n = 1 Output: true Explanation: 20 = 1 Example 2: Input: n = 16 Output: true Explanation: 24 = 16 Example 3: Input: n = 3 Output: false Constraints: -231 <= n <= 231 - 1 Follow up: Could you solve it without loops/recursion? Solution: We need to determine if a given integer n is a power of two. A number is considered a power of two if it can be expressed as 2x where x is a non-negative integer. The solution should efficiently check this condition without using loops or recursion. The approach leverages bit manipulation properties o…  ( 32 min )

Token Bucket rate limiter is one of the popular rate-limiter algorithms use to control number of requests sent to server. It work by maintaining a bucket which hold fixed number tokens, which will be refilled at a constant rate time. Each Request consume one token to processed. Let have a high level understanding. Meanwhile, system refill bucket with new token at a fixed rate(like 3 token/sec). But bucket can't hold more than it bucket capacity - so any extra tokens beyond that are discarded. Let consider a scenario where, within the a second there were requests are made, say 3 request. Before allow these request to proceed, rate limiter mechanism will checks system bucket tokens. Since tokens are available, all three requests are allowed, and three tokens are consumed from the bucket. Ho…  ( 8 min )

In mobile application development, routing and navigation are core mechanisms for implementing page transitions and user navigation experiences. Flutter provides a comprehensive routing management system that easily enables functionality like page switching, parameter passing, and data return. This lesson will detail the routing and navigation mechanisms in Flutter, helping you master various implementation methods for page transitions. Routing management in Flutter is based on a stack data structure, using the Navigator widget to manage a route stack, enabling push and pop operations for pages. Navigator is the core component for managing routes in Flutter. It maintains a stack of routes, where each route corresponds to a page: When a new page opens, its corresponding route is "pushed" …  ( 12 min )

I have been a happy user of the Vector database Pinecone, which provided me with a truly 'serverless' experience.

Ensemble Methods: Unleashing the Power of Boosting (AdaBoost and Gradient Boosting) Imagine you're trying to predict the weather. One meteorologist might look at the clouds, another at the wind patterns, and a third at historical data. Instead of relying on a single expert, wouldn't it be smarter to combine their predictions? That's the essence of ensemble methods in machine learning. Specifically, boosting is a powerful type of ensemble method that combines multiple weak learners (models that perform only slightly better than random guessing) into a strong learner with significantly improved accuracy. This article dives into the fascinating world of boosting, focusing on AdaBoost and Gradient Boosting. Ensemble methods leverage the power of "many heads are better than one."

The Problem with Weak AI Role Definitions If you have been experimenting with AI prompts, you may have encountered a recurring and frustrating issue: most role definitions are vague, generic, and ultimately ineffective. This is one of the most common mistakes in prompt engineering. Many users give their AI agent a loosely defined identity, then wonder why the responses feel bland, inconsistent, or disconnected from their intended outcome. A great AI prompt begins with a clear and well-crafted role definition. This establishes who the AI is, what it knows, and how it should respond. When the role definition is overly generic such as “You are a helpful assistant,” it squanders one of the most powerful levers in prompt design. Weak role definitions typically result in: Inconsistent tone and…  ( 6 min )

We’ve all been there — staring at the screen at 2 in the morning, wondering why the bug won’t go away, or why our code suddenly looks like an alien language. Late-night coding can be productive… or a complete nightmare. Here are 7 practical tips to keep your mind sharp and your sanity intact when you’re deep into those after-midnight coding sessions. 1. Set a “Soft Deadline” It’s tempting to keep going until you finish the feature, but your brain slows down at night. Set a cut-off time — even if you’re “just one line away” from solving it. 2. Keep Snacks & Water Nearby Midnight hunger is real. Avoid sugar crashes — go for nuts, fruits, or protein snacks instead of energy drinks. Your code will thank you. 3. Light Up Your Workspace Dim lighting might feel cozy, but it tricks your brain into sleep mode. Use bright, warm lighting to stay alert without straining your eyes. 4. Write “Future You” Notes If you’re too tired to continue, leave comments or TODOs in the code. Future you (a.k.a. 8AM coffee version of you) will be grateful. 5. Avoid Major Refactors At 2AM, you’re more likely to introduce new bugs than fix old ones. Stick to small, contained changes and leave the big rewrites for daylight. 6. Use Music for Focus Lo-fi, ambient, or even white noise can help you stay in the zone. Just skip songs with lyrics if they distract you. 7. Know When to Stop The golden rule: If you’re rereading the same line of code three times, it’s time to sleep. Your project will still be there tomorrow. 💡 Final Thought Late-night coding isn’t always bad — sometimes it’s when your creativity peaks. But don’t sacrifice your health (or sanity) for a few extra lines of code. What’s your personal “survival tip” for coding at 2AM? Share it in the comments — I’d love to hear what works for you.  ( 6 min )

There’s a saying: “Amateurs study tactics, while professionals study logistics.” In software, this translates to: “Amateurs focus on algorithms, while professionals focus on failures.” At J on the Beach, I took time in my talk to expand on this saying and explain that real-world systems don’t just need code that works on the “happy path” — they need a safety net for when things go wrong. Modern software development has layers of complexity. You’re not just writing code; you’re connecting systems across time and space, handling data that doesn’t sleep, and ensuring flawless performance at scale.

Recently, I explored two fascinating topics: The process of improving your website or content to rank higher in search engines like Google. It’s all about keywords, quality content, and making your site easy for both users and search engines to understand. A newer concept that focuses on making your content more discoverable by AI-powered search tools and chatbots (like ChatGPT, Perplexity, etc.). Instead of targeting only Google’s ranking, GEO ensures your content is AI-ready—structured, factual, and in a format that AI can accurately reference. SEO = Optimizing for traditional search engines. GEO = Optimizing for AI-driven answers. Future-ready content will need both. I’ll be exploring strategies that merge SEO and GEO to maximize visibility across both search engines and AI-powered platforms.

Introduction When I started building a small portfolio web app, I wanted a serverless backend. I didn’t want to manage servers, and I was studying for the AWS SAA certification, so I decided to give AWS SAM (Serverless Application Model) a try. Here’s a quick look at what it is and my impressions. AWS SAM is a framework for building serverless applications on AWS. With SAM, you can define your stack (Lambda, API Gateway, EventBridge, S3, etc.) in one YAML file and deploy everything with a single command. Developer Guide： What is the AWS Serverless Application Model (AWS SAM)? For my portfolio project, I wanted: A fully serverless backend to avoid maintenance. Hands-on AWS experience while preparing for the SAA exam. I also found SAM helpful because it handles API Gateway endpoints and EventBridge schedules in one place, which is much cleaner than configuring them directly in the console. Super easy to start The official tutorial + sam init = quick setup. Everything in code I can now manage the settings for both Lambda + EventBridge and Lambda + API Gateway in Git, unlike my previous console-based setups. Local testing gives confidence I can test endpoints and triggers locally before deploying. Python support is painless Just list dependencies in requirements.txt and deploy. If you’re building more than a few Lambdas. If you like clean, version-controlled infrastructure. If you want to test locally before pushing to AWS. AWS SAM made my portfolio project easier and more organized. If you’re learning AWS or want to explore serverless apps, I’d say: give SAM a shot!  ( 6 min )

This case study demonstrates how Model Context Protocol (MCP) allows AI agents to automate complete ETL workflows, without manual scripting. By exposing data pipelines as structured tools, MCP enables agents to extract, transform, and load data simply by following natural language prompts. This approach reduces integration complexity and helps teams move from code-heavy pipelines to fully orchestrated, agent-driven automation. Keboola’s MCP server turns Keboola pipelines into AI-callable tools. Agents can manage storage, run SQL transformations, trigger jobs, and access metadata—all with natural language. For example, a prompt like “Segment customers with frequent purchases and run that job daily” launches a full ETL workflow with built-in logging and error handling 12. # Example: initiat…  ( 7 min )

TL;DR The (Low)Code Maturity Model (LCMM) is a framework to classify how a technology team balances governance, flexibility, and delivery speed across three levels: Codeful – Full control over code, strict governance, and strong consistency. Low-deploy – A hybrid of code and low-code tools, enabling faster delivery while retaining some flexibility. Low-code – Tool-driven development with minimal coding, ideal for quick wins and non-developer contributions. Why it matters: Choosing the right level for each initiative helps avoid the extremes of slow, over-governed delivery or uncontrolled, unmaintainable quick hacks. When to use: Codeful → For core systems, high-risk domains, long-term maintainability, improving reusability, refactor of mature features. Low-deploy → For experimen…  ( 9 min )

Is Your Microservices Dream Turning into a Transaction Nightmare? You jumped on the microservices bandwagon for good reason: scalability, flexibility, faster development. But if you’re anything like the engineers I talk to, you’ve probably hit a brick wall. That wall? Distributed transactions. Suddenly, your simple online order isn’t so simple. It needs to talk to the inventory service, the payment service, the shipping service, and maybe even a loyalty points service. If one fails, what happens? Do you roll back everything? Do you leave things half-done? This is where the "transaction hell" begins. You’re not alone. Many teams try to solve this with complex two-phase commits (2PC) or other heavy-duty solutions. They end up with slow systems, tangled code, and a lot of headaches. It feel…  ( 9 min )

Short description Low coupling and high cohesion have been around for a long time as part of the GRASP patterns. However, the difference between coupling and cohesion is subtle. Many developers tend to mix them up, or understand only one (usually coupling) but not the other. cohesion and coupling as presented in Clean Code by Robert C. Martin. This note covers following questions: What’s the difference between coupling and cohesion? When does coupling become cohesion? Why can’t coupling exist without cohesion? Coupling and cohesion are closely related concepts. The confusion often comes from the language itself — the words sound similar and are sometimes used interchangeably in everyday conversation. Both measure communication or dependency between entities. The difference lies in the l…  ( 6 min )

This article is a repost of an ADR from Matanuska BASIC, my attempt to write a BASIC interpreter in TypeScript. The next feature to implement in Matanuska is looping. Classic BASIC's looping structures are... idiosyncratic, especially as compared to what's expected in a modern language. Therefore, we would like to compare what's offered by BASIC versus a modern language (in this case, Python), and make a decision based on these trade-offs. It is worth clarifying what design heuristics are important in this decision: Matanuska BASIC should loosely mirror classic BASIC dialects, such as MSX BASIC. Matanuska BASIC should support modern features, such as those in Python, as appropriate. Matanuska BASIC should be internally consistent. Design heuristics leveraged in its conditionals should also…  ( 9 min )

The AI era is not just a passing trend — it’s a paradigm shift that is completely rewriting how software is developed, deployed, and monetized. In the same way the internet created a new breed of millionaires in the early 2000s, and mobile apps did in the 2010s, today’s open-weight AI models are unlocking a new gold rush for developers.

👋 The Problem I Faced as a Developer & Creator A few months ago, I was working on YouTube content for a side project, and I kept hitting the same wall: getting real, actionable YouTube data without wasting hours. I tried a bunch of tools: TubeBuddy – Needed a Chrome extension and account login, UI felt bloated VidIQ – Limited features unless you paid, with constant upsells YouTube Data API – Required OAuth setup, had rate limits, and was overly complicated What I wanted was simple: A tool that just works instantly No signup, no download Support for Shorts, Videos, Channels, Trends Some AI help for summaries, tags, and insights So...

Let’s Start with the Truth Nobody Tells You Most “how to build a Webflow site” guides are copy-paste jobs. It’s not. The good news? “never touched Webflow” to a fully live website without begging a developer. The 3 Main Fears People Have Before Starting Webflow 1. “It looks way too complicated.” 2. “I don’t want to code.” 3. “I’ll screw it up.” Why Webflow is Worth Learning Instead of Wix/Squarespace Real control over design — you can adjust every pixel if you want. Clean, exportable code — unlike drag-and-drop builders that trap you. Built-in CMS — perfect for blogs, portfolios, or products. Grows with you — beginners can start simple, pros can build crazy animations. SEO-ready — not magic, but the tools are all there.

Packet sniffing isn’t always about listening to everything in the air. Sometimes, you want to focus on a specific Wi-Fi network — maybe for a security assessment, maybe for debugging. That’s where targeted sniffing comes into play. Let’s walk through how to do this effectively using airodump-ng, and how to dig into the results using tools like Wireshark. Imagine you’re in a location with dozens of Wi-Fi networks around. You're only interested in one — let’s call it MyTargetNetwork. If you sniff everything, you'll end up with a lot of noise. Targeted sniffing lets you capture only the traffic that matters, making analysis easier and more insightful. Start by putting your wireless adapter into monitor mode and scanning the area: airodump-ng mon0 You’ll see output like this: BSSID …  ( 7 min )

Congratulations! You have fallen prey to my clever click-bait-y title, but before you dismiss this topic out-of-hand ("Because," you say, "of course CSS has syntax"), or leave a smarmy comment, allow me to walk you through what CSS is, and how it's defined. Some context: I've been a maintainer of Less.js (the CSS pre-processor) for about 10 years, and the lead maintainer for most of that time. When I started contributing, I knew very little about not just CSS parsing, but about parsing in general. In the last 5 years, I've worked on not just Less but other CSS-related parsing projects, including one that re-imagines both Less and Sass parsing for the modern era (which has yet to be released). I've used a variety of parsing approaches, parsing generators, and parsing libraries. In some case…  ( 13 min )

If you’ve built a full stack app and want a super easy way to get it online, Render + Docker is a winning combo. In this quick guide, I’ll show you how I deployed my app using a Dockerfile on Render.com — with zero server config! A working app (Node.js, Python, etc.) A Dockerfile in your project root A GitHub repository A free account on Render Step 1: Create a Dockerfile Here’s an example Dockerfile for a Node.js app: # Use official Node image FROM node:18 # Set working directory WORKDIR /app # Copy all files COPY . . # Install dependencies RUN npm install # Start the app CMD ["npm", "start"] # Expose port EXPOSE 3000 For Python Flask, you might use: FROM python:3.11 WORKDIR /app COPY . . RUN pip install -r requirements.txt CMD ["python", "app.py"] EXPOSE 5000 Make sure to customize the Dockerfile for your tech stack. If you haven’t already: git init git add . git commit -m "initial commit" git remote add origin git push -u origin main Go to https://render.com Click New + → Web Service Connect your GitHub repo Render will auto-detect your Dockerfile Set the following: Name: Anything you like Environment: Docker Build Command: Leave empty Start Command: Use from Dockerfile Port: 3000 (or 5000 for Flask) Click Create Web Service Render will start building your image and deploy it automatically. Use .env file locally and set the same Environment Variables in Render Add a render.yaml file for Infrastructure as Code (optional) Set up automatic deploys on every GitHub push Monitor logs directly in the Render dashboard Docker + Render makes it dead simple to go from local development to live deployment. No AWS console, no NGINX config — just push and deploy. If you found this helpful, leave a like, share with your dev friends, or drop questions in the comments!  ( 6 min )

When working with GitHub, using HTTPS for pushing changes often asks for your username and password or personal access token every time. A better and more secure way is to use SSH authentication. This guide will show you how to generate an SSH key, add it to your GitHub account, and change your Git remote URL from HTTPS to SSH. Before generating a new SSH key, check if one already exists: ls -al ~/.ssh If you see files like id_rsa and id_rsa.pub or id_ed25519 and id_ed25519.pub, you already have SSH keys. You can skip to Step 3 if you want to use an existing key. If no key exists or you want to generate a new one, use the Ed25519 algorithm (recommended) or RSA as a fallback: For Ed25519 (recommended): ssh-keygen -t ed25519 -C "your_email@example.com" For RSA (if Ed25519 isn't supported):…  ( 7 min )

A new React application can be created using the create-react-app tool, which is a command-line utility. This tool automates the setup of a new React project, including the necessary file structure, configuration files, and build scripts. To create a new React app, follow these steps: Install Node.js and npm (Node Package Manager): If not already installed, download and install Node.js from the official website, which includes npm. Open a terminal or command prompt. Execute the create-react-app command: npx create-react-app my-react-app Replace my-react-app with the desired name for the application. Navigate into the project directory. cd my-react-app Start the development server. npm start Explaining Key Files public/index.html: src/index.js: src/App.js: src/App.css: src/index.css: package.json: node_modules/: This directory contains all the third-party libraries and packages required by the project, installed by npm.  ( 6 min )

Objective: This section explores containerisation and Infrastructure as Code (IaC) in AWS. We delve into Docker containers and how they solve deployment challenges, along with AWS ECS. We also examine the IaC service CloudFormation as a means for automating and managing cloud infrastructure through code rather than manual configuration! Containerisation is like filling an isolated box with everything an application needs to run — instructions, tools, and supplies. Once sealed, this box can be: Shipped to any environment (local, test, production). Duplicated to make identical containers. Opened/ran anywhere with consistent behaviour — eliminating the “it only works on my machine” problem! Image sourced from: https://www.xenonstack.com/insights/containerization Docker is a popular contain…  ( 7 min )

Objective: This section explores serverless architecture in AWS. We delve into its meaning and the associated services available in AWS, including Lambda (serverless functions) and API Gateway (serverless APIs) as means for building modern, cost-effective applications in the cloud. Serverless doesn't mean "no servers" — it just means we don’t manage them. AWS handles all the infrastructure provisioning, scaling, and maintenance of servers behind the scenes. We just focus on writing code or storing data! Serverless Examples: DynamoDB – Fully managed NoSQL database AWS Lambda – Run functions without managing servers API Gateway – Expose APIs to the internet without managing servers Here's an AWS Serverless overview, if you would like to dive deeper: https://aws.amazon.com/serverless…  ( 7 min )

Objective: This section looks into IAM and security fundamentals in AWS. We cover the role of IAM in controlling user access to AWS resources and monitoring AWS activity with services including CloudWatch and CloudTrail. IAM is AWS’s security layer for managing who can access what in our cloud account, and how they can do it. It fundamentally looks at Authentication (who are you?) and Authorisation (what can you do?). Principals (1) Root User When we first create an AWS account, we get a Root User - the account owner with full access to everything. This account should only be used for tasks including: setting up billing, emergency access, or creating initial IAM users or Identity Center setup. (2) IAM Users IAM Users are identities with permanent credentials (username/password or access …  ( 7 min )

Objective: This section dives into databases and builds upon the storage concepts covered in the Beginner's AWS Guide: Storage Services (Part 3). Here, we explore databases and look into RDS (relational databases) and DynamoDB (NoSQL) as popular service options available in AWS. A database is a system that stores, organises, and queries structured or semi-structured data at scale. Simple Library Analogy for Databases The library shelves = tables Academic books = structured data Magazines = semi-structured data Search system = query engine We don't just store data in a library — we organise and query it efficiently. This has its benefits, including being able to: Model relationships in data. Query data quickly and flexibly. Support multi-user reads/writes (multiple people using t…  ( 7 min )

Objective: This section introduces key cloud networking concepts, including Virtual Private Clouds (VPCs), Subnets, Internet Gateways (IGWs), NACLs, and Security Groups. By the end, you'll have a solid understanding of how AWS networking works behind the scenes and how cloud resources communicate securely. A Virtual Private Cloud (VPC) is like having our own private room in the AWS cloud - isolated from other AWS users. Inside this room, we can place resources like EC2 instances, databases, and more. By default, we're allowed up to 5 VPCs per region, but this limit can be increased. 💡 Each resource inside a VPC needs a private IP address so it can be uniquely identified, to send/receive data, and to avoid IP conflicts. When we create a VPC, we customise it by assigning: A name (e.g. de…  ( 7 min )

Objective: This section builds upon a key component of servers - Storage as covered in the Beginner's AWS Guide: Virtual Servers (Part 2). Here, we delve into the available data storage services in AWS, including S3, EBS, and EFS. Servers need a place to store and retrieve data, and in this case, AWS S3 is a very popular option. We can store and access many data types, including; Images (JPG, PNG) Documents (PDF, DOCX) Videos (MP4, MOV) Audio (MP3) Static files (HTML, CSS, JS) More precisely, S3 is an object storage service that allows us to store files (called objects) in buckets, which act like top-level folders, and to access objects directly via URL. Each object can be up to 5TB in size, and buckets can hold an unlimited number of objects. Each object consists of: The data itself (e…  ( 8 min )

Objective: This section explores virtual servers in the cloud, and their role in cloud operations. Here, we dive into managing virtual servers using AWS's primary service, the Elastic Compute Cloud (EC2), along with Elastic Load Balancing (ELB) for distributing traffic and Auto Scaling Groups (ASG) for automatically managing server capacity. Amazon EC2 is a service that provides scalable virtual servers (called instances) in the cloud. These virtual servers run on physical hardware in AWS data centres, but we don't need to manage or buy the hardware itself. Thanks to a software layer called a hypervisor, multiple virtual servers (EC2 instances), including those from different AWS customers, can run safely and independently on the same physical machine! Simple Analogy: The physical server…  ( 7 min )

Participating in a global engineering competition taught me more than any classroom lecture. Here are five key lessons I learned as a WorldSkills competitor in Railway Systems Technology: Hands-On Skills Trump Theory: You can recite rail engineering theory all day, but building a functioning circuit or fixing a brake system on the spot is a different challenge. I spent months beforehand getting my hands dirty with real equipment, which paid off during the competition. Precision and Safety are Paramount: In railway systems, a small error can cause big problems. I learned to double-check every nut, bolt, and line of code against safety standards. This attention to detail became a habit that improved all my projects. Embrace New Technology: I'm exposed to integrated IoT sensors to monitor train components in real-time. It was my first time learning with industrial IoT, and it showed me how emerging tech (like sensor networks and data analytics) can revolutionize old industries like rail transport. Teamwork & Leadership: Engineering is a team sport. In the heat of competition, I stepped up to coordinate tasks and troubleshoot issues under pressure. Leading a team of peers taught me how to communicate clearly and keep everyone calm when stakes are high. Global Networking: WorldSkills introduced me to peers and experts from around the world. Sharing ideas with an industrial simulation designer from Jiean Hi Tech and a maintenance specialist from CRRC broadened my perspective on engineering problems and solutions. These lessons continue to shape my career. For any engineering student or young professional, competitions and hands-on projects are invaluable – they push you beyond your comfort zone and fuel real growth.  ( 6 min )

Hi! Assuming you know what time tables are and you need to have them in SQLite, here's how we can generate one: WITH RECURSIVE cnt(x) AS ( VALUES(unixepoch('2025-01-01 00:00:00')) --> Start datetime. UNION ALL SELECT x + 60 --> Period duration, in seconds. FROM cnt WHERE x End datetime. ) SELECT x AS start, x + 59 AS stop --> Also period duration, minus last second. FROM cnt; The code above will generate 181 rows of start - stop pairs since 2025-01-01 00:00:00 till 2025-01-01 03:00:00. Each pair represents a 1-minute interval (left end included, right end excluded). Obviously, you can change the interval to be anything, just don't forget to update it in both places. Full example with saving to an actual time table: CREATE TABLE periods_1m (start INTEGER PRIMARY KEY, stop INTEGER); WITH RECURSIVE cnt(x) AS ( VALUES(unixepoch('2025-01-01 00:00:00')) UNION ALL SELECT x + 60 FROM cnt WHERE x < unixepoch('2025-01-01 03:00:00') ) INSERT INTO periods_1m (start, stop) SELECT x, x + 59 FROM cnt; Resources: SQLite docs on WITH clause and recursive CTE blog post by Brady Holt, which pushed me to finally read the SQLite docs above (: Bye!

When growing up, I really wanted to be a footballer. I had the talent plus the passion in football. Back in high school, I used to save my pocket money to get good football boots and just write formation mostly during inter-classes games skipping doing assigments. Football to me was more than passion; it didn't work out as expected. Sometimes I sit down to reflect on my football days and say I could do best, especially when I go to Kasarani stadium to watch games. Back in the day, I had a chance to train with Austin Odhiambo (Roll Royce) when he was still at FC Leopard junior Team before transitioning to the FC Leopard Senior Team. I didn't train a lot with them due to not having consistency because of some challenges. I'm really happy to see him shine for our national team. In school, I w…  ( 8 min )

In Lodash, _.omitBy creates a new object by removing properties where the predicate function returns true. _.omitBy is only for objects (key–value pairs), not for arrays of values. What omitBy Does Loops over each property of the given object. Runs your predicate function for every (value, key). If predicate returns true, that property is removed from the new object. Returns a new object (does not modify the original). Think of it as the opposite of _.pickBy — instead of keeping matching properties, you remove them. Basic Example import omitBy from 'lodash/omitBy'; const obj = { name: 'Ola', age: 0, active: false, city: null }; const result = omitBy(obj, (value) => value == null); // removes `null` and `undefined` console.log(result); // { name: 'Ola', age: 0, active: false } How the Predicate Works (value, key) => { // value → the property value // key → the property key as a string } Example: omitBy(obj, (value, key) => key === 'age'); // removes any property where the key is "age" Common Uses Remove null or undefined fields omitBy(obj, value => value == null); Remove all falsy values (false, 0, '', null, undefined, NaN) omitBy(obj, value => !value); Remove keys by name pattern omitBy(obj, (value, key) => key.startsWith('_')); // removes any key starting with underscore Difference from omit omit → remove by key names you already know: **_.omit(obj, ['age', 'city']);* omitBy → remove by a condition (calculated dynamically for each key).  ( 6 min )

When you build applications in React, your components don’t just magically appear and stay static — they live and die in a predictable order of events. This process is called the component lifecycle. In simple terms, a component goes through three main stages: Mounting – when it’s created and inserted into the DOM. Updating – when it changes in response to new data or props. Unmounting – when it’s removed from the DOM. Knowing this sequence is key to writing components that handle setup, updates, and cleanup without bugs. One. The Lifecycle in Class Components A. Mounting – First appearance on the screen static getDerivedStateFromProps() – Sync state from incoming props (rarely used in modern React). render() – Return the JSX that describes the UI. componentDidMount() – Runs after the comp…  ( 6 min )

Hi everyone 👋 I’m John Atkins, a product designer with 20 years of experience. Over my career, I’ve worked on everything from large SaaS platforms to niche productivity tools. Now that I’m retired, I still enjoy tinkering with small ideas, turning them into real products, and sharing them with others. Recently, I found myself frustrated with browser bookmarks. I’m a heavy bookmark user — saving articles, tools, and references almost daily — but the default bookmark manager is clumsy. Long titles get cut off, there’s no clear “date saved” info, and finding that one link from “last Tuesday” is a headache. So, I built a Chrome extension called Magic Bookmark. You can check it out here: https://bit.ly/3UjCFeg What it does: Offline snapshots — See titles, icons, and last-visited dates even when offline. Smart grouping — Automatically groups bookmarks by “Today,” “Yesterday,” and older, so recent saves are easy to find. Two-line titles — More context at a glance, no more guessing what a link is about. It’s a small, quiet tool that lives in the background, helping keep bookmarks neat without extra work. If you’re curious, try it and let me know if it makes your workflow smoother. And I’m wondering — do you use browser bookmarks at all, or do you prefer tools like Notion, Raindrop, or Pocket to manage your personal knowledge base?  ( 6 min )

I recently led an engaging hands-on workshop at ABBYY DevCon 2025. The session, "Creating a Document Processing MCP Server," was crafted for developers eager to explore advanced workflow automation, focused on constructing a Model Context Protocol (MCP) server tailored for intelligent document processing (IDP) tasks. MCP is one of the hottest technologies in the AI ecosystem, so I was thrilled to give a presentation on its fundamentals.

Today was one of those days that makes you question every life choice that led you to stare at a computer screen. I woke up with this brilliant plan to ditch the mini projects I'd been convincing myself I needed and just dive into building my main project with React and Tailwind. Sounds reasonable, right? What followed was 8 hours of moving at the speed of dial-up internet. Every line of code felt like lifting weights underwater. Simple concepts that should click instantly became these massive mental blocks. The worst part? Scrolling through everyone else's builder feeds. Everyone's shipping features, learning new frameworks, celebrating wins. Meanwhile, I'm over here like "I successfully imported React today, where's my trophy?" It's funny how we forget that behind every "crushed my goals today" post are probably ten days of staring blankly at documentation, wondering if we've lost the ability to think. This is the part of building in public that doesn't get hashtagged. The days when your brain feels like it's running on Internet Explorer. When you convince yourself you need seventeen practice projects before touching the real thing. I spent today questioning why I'm not moving as fast as everyone else seems to be. But here's the thing - maybe everyone else is having these days too, they just don't post about them. Saturday and Sunday are now officially dedicated to making up for today's snail-pace adventure. No more overthinking, no more "I need to learn X before I can do Y" nonsense. Sometimes the most honest thing you can admit is that today was rough, but you're still showing up tomorrow. Because even slow progress is still progress, even when it doesn't feel like it.  ( 6 min )

Introduction Hey fellas, welcome back to another blog today. I am going to tell you how you can use SpriteSheet in Mini Micro. So let's dive in by first understanding what a SpriteSheet is and then implementing one in Mini Micro. A spritesheet is basically a single big image that contains multiple smaller images(aka sprites) used in 2D games. The images contained by the sprite sheet are frames of individual animations of a sprite. Let's say our game has a zombie sprite with the following animations: Hit (When it attacks the player) Hurt(When player attacks it) Die Walk Idle Let's suppose each animation has 3 frames. So there are a total of 15 frames (Number of Animations * Frames in each animation) Now, saving these 15 separate frames in separate image files is chaotic; your file …  ( 6 min )

Sony’s CFO Lin Tao has admitted that its big bet on live-service games “is not entirely going smoothly,” pointing to the historic flop of Concord (shut down weeks after launch) and the indefinite delay of Bungie’s Marathon after ugly playtest feedback and stolen-artwork drama. Even Fairgame$ got pushed to 2026 following internal backlash. Still, Sony isn’t throwing in the towel—they’ll lean on hits like Helldivers 2, MLB The Show, Gran Turismo 7 and Destiny 2, which together make up 20–40% of their gaming revenue. Tao says the plan is to learn from these stumbles, cut waste and keep pushing more polished live-service experiences in the years ahead.  ( 5 min )

You know that moment when you’re in the middle of nowhere, your 4G turns into “E”, and your mobile app decides to become a very expensive paperweight? Yeah. That’s exactly why I wrote this. Picture a delivery driver staring at a loading spinner because the app can’t load their route without internet. Or a warehouse manager unable to pull the inventory list because the server’s down. That’s not “quirky behavior,” that’s lost time, lost money, and very angry users. A bunch of our clients hit these connectivity potholes — remote job sites, offsite events, warehouse floors, logistics hubs. Basically, anywhere Wi-Fi goes to die. The fix? Local-first apps: process data locally, sync it when you can. Your users stay happy, and you don’t get midnight “the app’s broken” calls. In this little advent…  ( 11 min )

EA’s pulling the plug on four of its games this October, and once they’re gone, they’re gone for good. The shutdown schedule is: October 6: NHL 21 October 7: Need for Speed Rivals (the 2013 racing entry with a middling 75–80 Metacritic score) October 20: Madden NFL 22 October 30: FIFA 23 All online services will cease across PC, PlayStation (4 & 5), Xbox (One & Series X/S) and Nintendo platforms (Switch & future Switch 2). EA hasn’t explained why, but it usually boils down to licensing and server costs. After the cutoff, there’s no coming back—unless the nostalgia gods bless NFS Rivals with a future remaster (and even that’s a big “maybe”).  ( 5 min )

Valve and Mastercard are duking it out over who’s really behind the recent purge of adult/NSFW games from Steam (and Itch.io). Mastercard insists it never pressured any platform to delist games and that it “allows all lawful transactions.” Valve, however, says their payment processors blanked on legal adult titles by waving around Mastercard’s Rule 5.12.7—which bans anything that “may damage the goodwill of the Corporation”—and that those processors cited it explicitly when demanding removals. Meanwhile, other players in the saga are pointing fingers, too: Stripe claims it was simply following banks’ own restrictions, and the only group cheering loudest is the activist Collective Shout. In the fallout, Valve reluctantly complied, while Itch.io has already relisted dozens of free games and is hunting for friendlier payment partners for paid NSFW content.  ( 5 min )

Baldur’s Gate 3’s own Aliona Baranova (voice of Corinna the Squirrel and performance director) says it’s about time film and TV adaptations of video games start tapping the people who bring those worlds to life. Sure, studios are cashing in on our favorite franchises—but Baranova argues that when it comes to casting, video game actors are being totally “slept on.” Speaking at FanX’s Tampa Bay Comic Convention, she pointed out that hardcore gamers are the ones driving these adaptations’ success, yet Hollywood keeps overlooking that passionate fanbase. As she put it, “Why are we not being considered when there’s video game adaptations?”  ( 5 min )

Rockstar is said to be adding age-verification checks to GTA Online in the UK, after dataminer Tez2 discovered hints in the game files. Players might have to prove they’re over 18 before accessing the full online suite – things like phone messages, text chat and Snapmatic could be locked behind an age gate, while younger users get cut off entirely. This move looks like a direct response to the UK’s Online Safety Act, which has forced social platforms (and adult sites) to verify users or face hefty fines and possible bans. Since GTA Online already carries an 18+ rating but lacked any real checks, it makes sense that GTA 6’s online mode (due May 2026) will follow suit to keep the game legal in one of its biggest markets.  ( 5 min )

Peak’s indie devs just dropped a bomb: they’d rather you pirate their hit climber than waste time on Cliff, a Roblox knock-off they call “microtransaction-riddled ripoff slop.” Cliff apes Peak’s art, lobby design, first-person climbing and even the stamina bar—and slaps on paywalls galore. On X, Team PEAK urged fans to skip Cliff entirely, preferring piracy over supporting a shameless copy. Sure, Roblox is full of “inspired” games, but Cliff really leans into straight-up copy-and-paste territory. (Meanwhile, Peak recently got dark, adding a cannibalism feature so you can literally snack on your friends.)  ( 5 min )

GOG just kicked off its cheekily named “Freedom to Buy” campaign, plastering 13 once-controversial games on a special site (FreedomToBuy.games) and handing them out free for 48 hours. The stunt’s all about shining a spotlight on what they call “quiet” censorship—titles getting quietly delisted not for breaking laws but for making someone, somewhere, uncomfortable. Among the freebies you’ll find everything from POSTAL 2 and Agony to HuniePop and House Party. GOG’s big point? If a game’s legal and responsibly made, you shouldn’t need a secret handshake to grab it—yesterday, today or decades from now.  ( 5 min )

The Convergence of Physical and Digital Security As organizations increasingly adopt interconnected systems, the line between physical and digital security is blurring. Traditional methods that treat employee badge access and digital authentication separately no longer provide sufficient protection against today’s sophisticated threats. This convergence is accelerating the shift toward passwordless, phishing-resistant authentication methods—most notably, the use of passkeys in enterprise environments. Physical badges have evolved from basic RFID/NFC cards, which simply transmit static identifiers, to advanced FIDO2-compliant smart cards capable of functioning as cryptographic authenticators. These new-generation smart cards are compatible with open standards like WebAuthn, enabling secur…  ( 6 min )

Eight years ago, I was a junior developer writing my first console.log("Hello World"). Today, I’ve led engineering teams, mentored dozens of developers, and built products across industries.

A report by Pantera Capital has recorded a fundamental shift in how the crypto industry pays its employees. Over the past year, the share of professionals receiving salaries in digital assets has tripled, but the real story lies in the details: Circle's USDC stablecoin has confidently displaced its main competitor, Tether's USDT, as the preferred means of payment. Infrastructure is more important than hype The new crypto-labor economy Practice beats theory: In the blockchain sphere, practical experience is valued more highly than formal education. Specialists with a bachelor's degree earn significantly more ($286,039) on average than those with master's ($214,359) and doctoral ($226,858) degrees. The industry pays for real skills, not diplomas. Engineers on the rise: Salaries for technical specialists, especially entry-level and mid-level, have shown impressive growth (25.6% and 14.5%, respectively), indicating an acute shortage of qualified personnel. Back to the office? Although remote work remains the norm (82%), the share of employees working in the office on a permanent basis has quadrupled in a year, from 1.5% to 6%. This may signal the gradual emergence of more traditional corporate structures within leading companies. Thus, the choice of USDC as a “salary” standard is not a coincidence, but a reflection of a deep trend toward the legitimization of the crypto sector. The industry is moving from the “Wild West” era to building a stable and predictable financial system, and the choice of tools for this speaks for itself.  ( 6 min )

You really shouldn’t have your phone in bed. But I can’t help myself. Every night, long after I should be asleep, I find myself lost in an endless scroll. It's not TikTok, Instagram or even X. Sometimes i go for hours. And if my wife catches me, hell brakes loose. I have a confession to make: I doom-scroll real estate at night. Gorgeous homes, dreamy interiors… and tragically, photos taken with a potato. Why are these listings so bad? Curious, I dove into the r/realestatephotography subreddit. Every other post sounded the same: “How do I find clients?” “Where do I get leads?” And that’s when it hit me. There’s a real need here, on both sides. Agents want beautiful photos to help sell homes. Photographers want reliable, paying clients. So, as an experiment, I created a Reddit ad with a bold title: “Find Clients Here.” And promoted the Ad in the subbreddit I expected a few clicks. Maybe a couple of curious photographers. Instead, signups started pouring in. That’s how PropPhoto.com was born. A platform that connects real estate agents with vetted photographers, streamlining everything from discovery to delivery. What started as a late-night obsession turned into a real product. A SaaS business. One that solves a real problem for real people. And it all began with doom-scrolling  ( 5 min )

I've been testing the model since its release on various tasks: Complex agent workflow for Voice AI: This application has various chains of prompts and advanced techniques to guide users through their meal order. Model performs okay; it seems to be on par with Claude 4, but still gets about 16% of the orders wrong. Claude was scoring around the same.👌 Edit an existing game: I prompted Claude 3 times to fix a particular bug with collision detection. You basically tap floating objects, and some pop to reveal surprises. One of the issues was touch sensitivity; on some objects, you have to tap 3-4 times before it marks the object as collected. Claude Sonnet could never fix this issue after 3-4 prompts, GPT-5 one-shot fixed it✅. General coding tasks: "Randomly select a product from a list of p…  ( 6 min )

Have you ever heard the word volatile in Java and thought, "Aha! This is my magic bullet for concurrency issues!"? Well, you're not alone. Many developers, especially when just starting with multithreading, see volatile and think it's the ultimate fix. But here's the truth: volatile is powerful, yes, but it's also often misunderstood and can actually hide deeper problems in your code if you rely on it blindly. Let's break down why your perceived concurrency 'fix' might be secretly lying to you, and what to do about it. volatile: What It Actually Does First, let's understand what volatile promises and delivers. When you mark a field as volatile in Java, you're telling the Java Virtual Machine (JVM) two crucial things: Visibility: Any write to a volatile variable by one thread is immediat…  ( 8 min )

In the shadow of towering skyscrapers and amidst the hum of smart buildings, a quiet revolution is unfolding. The real estate industry—historically resistant to technological change—stands at the precipice of transformation. Artificial intelligence isn't merely automating mundane tasks; it's fundamentally restructuring how property is valued, transacted, managed, and experienced. As predictive algorithms increasingly replace gut feelings, and virtual assistants render traditional viewings obsolete, we're witnessing the emergence of an entirely new property paradigm. This isn't simply about efficiency gains or cost reductions—though these certainly feature—but rather a profound reimagining of our relationship with the spaces we inhabit. By 2025, AI won't just be a feature of real estate; it…  ( 14 min )

The rapid evolution of AI models means that what was groundbreaking yesterday can seem outdated today. This is the case with Anthropic’s Claude 3.5 Sonnet and its newer version, Claude 3.7 Sonnet. If you’re wondering which one to choose or just want to know what’s different, here’s a simple breakdown. The biggest change is 3.7’s hybrid reasoning model. Unlike 3.5, which gives quick answers, 3.7 allows you to switch between standard mode for fast responses and an “extended thinking” mode. In this mode, the model takes extra time to reason through problems step by step. This is great for difficult coding, math, or complex analytical tasks. This approach helps users manage the depth and speed of their answers, adjusting based on cost or performance needs. Real-World Task Mastery Claude 3.7 is…  ( 6 min )

Alembic is a Python tool that integrates with the SQLAlchemy ORM to apply model changes to relational databases such as PostgreSQL, MySQL, and Oracle. It supports both online migrations (recommended for development and UAT environments) and offline migrations (recommended for production). However, Alembic does not support NoSQL databases like MongoDB or DynamoDB. For example you have a db model that you would like to migrate run the below command in the terminal pip install alembic You will find the migrations folder and the alembic.ini file in the project directory. Please note: In this example, I've used SQLModel, which is a wrapper around SQLAlchemy. If you're working with SQLAlchemy directly, make sure to use SQLAlchemy's own metadata. Once done run the below command to generate the initial revision file. alembic revision --autogenerate -m "initial migration" Go to migrations > version > revision file and verify the auto generated code. Resolve the error if any. Run the below command and verify the generated tables in database alembic upgrade head In my case table were created successfully. Suppose you want to remove a column from a table. Execute the following command. It will generate a revision file, as illustrated below. alembic revision --autogenerate -m "remove gender" Run the below command to apply the changes. alembic upgrade head def upgrade() -> None: Scenarios Where You Use upgrade() Scenarios Where You Use downgrade() You add a gender column (upgrade). Run the command to re-add the column. To revert one step: alembic downgrade -1 alembic downgrade base Always reverse changes in the opposite order of upgrade(). If your upgrade() creates something, downgrade() should drop it. If your upgrade() drops something, downgrade() should recreate it. Always include foreign key handling when applicable.  ( 6 min )

Fine-tuning has emerged as a cornerstone technique in the development and deployment of high-performance artificial intelligence models. As AI applications become more specialized and demand higher accuracy, fine-tuning enables organizations to adapt large, pre-trained models to their unique data, domains, and tasks, thereby bridging the gap between generalized AI capabilities and bespoke business needs. What Is Fine-Tuning? Fine-tuning involves taking a pre-trained AI model—typically trained on massive, diverse datasets—and continuing the training process using a smaller, domain-specific dataset. This process adjusts the model’s parameters to better align with the nuances, terminologies, and distributions present in the target environment. By leveraging the generic knowledge embedded in t…  ( 6 min )

Processing vast amounts of data in real-time, known as stream processing, is at the heart of many modern applications. Think about fraud detection, personalized recommendations, or monitoring system health – these all rely on quickly crunching continuous streams of information. For Java-based systems that handle this, the Java Virtual Machine (JVM) is your engine. But just like any powerful engine, if it's not tuned correctly, it can consume too much fuel – in this case, memory. A large "memory footprint" (how much memory your program uses) can lead to serious headaches for high-throughput stream processing. When your JVM uses too much memory, several problems pop up, especially under heavy load: Garbage Collection Pauses: The JVM has a built-in "garbage collector" (GC) that cleans up un…  ( 9 min )

This is a cross-post, you can find the original article on my Medium Embedding similarity is the backbone of modern AI applications that understand meaning rather than just matching words. By representing text as vectors, it allows you to measure how semantically close two pieces of content are — even when they share no common terms. This powerful capability enables more accurate search, smarter recommendations, and deeper insights from your data. Embeddings are a way to represent text as a semantically meaningful vector of numbers. For example, the embeddings of "I love programming in Python" and "I like coding in a language whose symbol is a snake" should be similar despite the fact that the texts have practically no words in common. semantic similarity as opposed to syntactic similarity…  ( 8 min )

Complex Query Handling in CQRS: Minimizing Roundtrips and Latency with Projection Materialization CQRS (Command Query Responsibility Segregation) is a pattern that separates read and write operations for a data store. This separation allows you to optimize each side independently, leading to improved performance, scalability, and security. However, when dealing with complex queries, especially those requiring data from multiple sources or complex calculations, a naive implementation of CQRS can lead to increased roundtrips to the database and, consequently, higher latency. This blog post explores how projection materialization can help minimize these issues, making your CQRS implementation more efficient.

As a C++ developer in natural language processing (NLP) or machine learning (ML), you've probably hit the tokenization wall. Tokenization, more specifically splitting text into words, sub-words, or characters is critical for models like BERT or DistilBERT, but most C++ tokenizers are either slow, bloated with dependencies, or choke on Unicode. That's why I built Modern Text Tokenizer, a header-only, UTF-8-aware C++ library that's fast, lightweight, and ready for ML pipelines. In this tutorial, I'll show you how to set up Modern Text Tokenizer, integrate it into your C++ project, and use it to preprocess text for NLP tasks.

In today's interconnected world, seamless digital access is everything. Yet, many businesses and individuals face constant frustration: getting blocked by websites, facing account suspensions, or having their access suddenly restricted. These issues often stem from one core problem—the reputation of your IP address. The ultimate goal is to have your connection treated as trustworthy, essentially placing it on a digital "ISP whitelist." Websites and online services use sophisticated systems to filter traffic. They maintain internal "blacklists" for IP addresses that have been associated with suspicious activity. Using a shared or low-quality IP can easily get you flagged, as another user on the same IP may have violated terms of service. This leads to frustrating CAPTCHAs, access denials, a…  ( 7 min )

The e-commerce market in Africa is on the rise and is expected to grow by 34% annually through 2025, with over 500 million digital buyers. It’s a massive opportunity. But despite the impressive growth, many businesses still struggle to turn this potential into actual sales, often because they fail to take local preferences into account. Most businesses offer multiple payment methods, but often they don’t align with what people actually use. Prices are sometimes listed in unfamiliar currencies, which throws users off and makes the experience feel disconnected. Consider the diversity across the continent: 54 countries, over 2,000 languages, and a wide range of payment systems. That kind of variety means a one-size-fits-all approach simply doesn’t cut it anymore. In this guide, you’ll learn w…  ( 12 min )

Mastering Construction Management: The Essential Guide to a CMP A Construction Management Plan (CMP) serves as the strategic playbook for any construction project, acting as a formal document that outlines how the project will be executed, monitored, and delivered. By aligning all stakeholders on goals, timelines, and responsibilities, a CMP is the single source of truth that helps prevent chaos and miscommunication throughout the construction process. Think of trying to build a skyscraper without architectural plans—that chaos is what happens in construction without a well-structured CMP. This plan is crucial for managing the four pillars of every project: cost, time, quality, and safety. Each pillar supports the others, and neglecting one can jeopardize the entire project.

Today’s Learning: Installed MySQL for database management. Solved The Minion Game challenge on HackerRank in Python. 1️⃣ Installing MySQL MySQL is one of the most popular relational database management systems. Today, I learned how to install it on my system to start practicing SQL queries for Data Analytics. Steps I followed: Downloaded MySQL Community Edition from the official MySQL website. Installed MySQL Server and MySQL Workbench. Configured root username and password. Verified the installation by running: mysql --version Opened MySQL Workbench and successfully connected to my local server. ✅ Now I’m ready to write and execute SQL queries directly in MySQL Workbench. 2️⃣ HackerRank Challenge – The Minion Game 🐝 The Minion Game is a fun string-based game where two players, Kevin and Stuart, compete based on vowels and consonants in a given word. Rules: Kevin gets points for substrings starting with vowels. Stuart gets points for substrings starting with consonants. Python Solution: def minion_game(string): vowels = 'AEIOU' kevin_score = 0 stuart_score = 0 length = len(string) for i in range(length): if string[i] in vowels: kevin_score += length - i else: stuart_score += length - i if kevin_score > stuart_score: print("Kevin", kevin_score) elif stuart_score > kevin_score: print("Stuart", stuart_score) else: print("Draw") # Example minion_game("BANANA") Step-by-step logic: Identify vowels – If the current letter is a vowel, Kevin gets points. Points calculation – Number of substrings starting at position i is length - i. Score comparison – After looping, compare Kevin’s and Stuart’s scores. Output for BANANA: Stuart 12 💡 Today’s Takeaway: Installing MySQL is the first step toward mastering databases in Data Analytics. String problems like the Minion Game help improve Python logic, which is essential for data processing.  ( 6 min )

In today's digital landscape, website security is non-negotiable. One of the most effective ways to defend against common attacks like Cross-Site Scripting (XSS) and data injection is by implementing a Content Security Policy (CSP). A CSP acts as a powerful gatekeeper, telling a user's browser exactly what resources are allowed to load on your site. This simple, yet powerful, layer of defense can prevent malicious scripts from executing, even if an attacker manages to inject them. So, how do you set up a CSP and make your site more secure? Let's dive in. At its core, a CSP is a security standard that web developers can use to define a set of policies for their web pages. These policies tell the browser which sources are trusted for various types of content, such as scripts, stylesheets, im…  ( 7 min )

✨ What is a Trie? A Trie (pronounced like "try") is a special type of tree used to store strings, particularly useful for prefix-based lookups. Unlike typical trees, each node in a Trie represents a single character, and paths down the tree represent strings. Think of it like an autocomplete brain — super efficient at saying: "Do any words start with 'hel'?" or "Does this word exist exactly?" 🔍 Fast word search 📜 Efficient prefix matching (perfect for autocomplete!) ⚡ Can handle thousands of strings efficiently 🧠 Great for dictionary-like problems We’ll use a simple object-based structure (instead of a class-based node) to keep it lightweight and readable. var Trie = function () { this.root = {}; }; this.root is the base of our Trie. Each key in the nested objects is a letter. At…  ( 12 min )

After 20+ years as a software developer, I can attest that "it works on my machine" is still one of my most used catchphrases, even when I have a slight hint as to its inaccuracy. It's become a safety blanket in a sea of uncertainty and poorly refactored code. This five-word phrase has become the ultimate shield in code reviews, bug reports, and failed live demos. And for a good reason. It actually works. Most non-developers staring at a developers workstation will see a combination of IDE's, console windows, database monitoring tools and hidden YouTube videos slightly off screen. That chaos mixed with "it works on my machine" give off this aura of elevated complexity that most people would rather not be a part of.

Efficiently Handling Large Result Sets with Java Streams and Database Cursors Imagine you're building a system that needs to process millions of records from a database. Directly loading all that data into memory can quickly lead to performance bottlenecks, or even application crashes due to OutOfMemoryError. Fortunately, there's a powerful combination: Java Streams and Database Cursors. This article explores how to use these tools effectively to manage large result sets without overwhelming your application. Traditional database queries often load the entire result set into memory. This is acceptable for small datasets. However, when dealing with tables containing millions or billions of rows, this approach becomes unsustainable.

When was the last time you deployed a rate limit change without fearing you'd break something? Basic rate limiting is easy: A single line in nginx, a middleware in Express, or a throttling rule in AWS API Gateway. But here’s what happens next: A single client accidentally fires 1000 requests per second and burns your budget. You deploy a new limit — and break an integration with a key partner. You realize you have no idea which rules are working, and which are dead code. Most rate limiting is: ❌ Opaque – you don’t know who was limited or why ❌ Static – same rule for everyone ❌ Hardcoded – changes require code + deploy ❌ Disconnected from business – all users treated equally, even if they pay very differently product feature Imagine this: You can dry-run a new limit and see exactly who would be affected — before rolling it out.

The internet ate the world of bits. Now it's coming for atoms. Humanoid robots are breaking out of the lab and onto the factory floor. The founders building them speak with quiet inevitability. The tech still trips, stumbles, and drops things—but the consensus is clear: these are temporary bugs, not permanent blockers. The breakthroughs are close enough to smell. The transformation feels inevitable because the economics are relentless. We're witnessing the early stages of what could be the most significant industrial revolution since the assembly line. In 2025, only ~150 humanoid robots are in active U.S. pilots—Tesla in factories, Amazon's Digit, BMW's Figure-01, Mercedes-Benz's Apptronik. But the pattern is familiar: 20 robots in a pilot By 2030, our internal model projects ~820,000 huma…  ( 8 min )

When I decided to “learn to code,” I pictured myself sipping coffee in a minimalist loft, building the next billion-dollar SaaS in a week. Here’s the thing about starting your coding journey: it’s messy, hilarious, and kind of like playing chess against a smug robot. You think you’ve won, then JavaScript pops up and says: “LOL, nope. Missing a semicolon, human.” Phase 1: The Overconfidence Stage Phase 2: The Existential Crisis Phase 3: The Breakthrough Moment That’s why I started documenting my journey and sharing tools, wins, and facepalm moments at Income Hub 247 — because whether you’re here to build a SaaS, automate your business, or just finally learn what an API does… the journey is way better when you don’t take yourself too seriously. Pro tip: Save every embarrassing bug. They make great stories for when you’re rich, famous, and still unable to center a div without Googling it.  ( 6 min )

Why precise asset tracking matters Ultra‑Wideband fundamentals UWB is also secure. Its physical layer uses AES encryption and scrambled timestamp sequences to prevent relay attacks. These properties make it suitable for digital car keys, secure building access and precision asset tracking. UWB vs. Bluetooth LE positioning UWB’s centimeter‑level precision and strong security come with slightly higher cost and power usage than BLE. The choice depends on application requirements: high‑value asset tracking, robotics and augmented reality benefit from UWB, whereas low‑cost tags and simple presence detection often suffice with BLE. TinyML and Edge AI: bringing intelligence to the edge Advantages and challenges Case study: predictive maintenance with TinyML Integrating UWB and TinyML for smart as…  ( 10 min )

I build a lot of websites and sifting through JSON data in the console sucks. so I made a tool called JSONBason to convert a JSON object directly into a searchable, sortable table. Plenty of these tools exist already, the difference here is that JSONBason's API takes in JSON data directly from my dev site's app code so I don't have to upload a CSV or copy/paste the JSON. The 'id' or kind of user id which is just a session id is destroyed each time JSONBason is reloaded, only your session id can see the JSON you send to it. It's totally free and open, no sign up and you can test it out below: Grab the code snippet from https://jsonbason.com and paste it into your dev code (yours will always be different with a unique id.) // =========== JSONBason-DEV-use-only =========== const myData = [{"Welcome":"1","To":"2","JSONBason":"3"}]; fetch('https://jsonbason.com/api/json', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ id: 'BBvbvbsPBPGa4ypMnFxK', JSONdata: myData }) }) .then(r => r.json()) .then(data => { console.log('Sent to JSONBason OK'); }) .catch(console.error); Modify the myData variable to your JSON array and send in JSON data. It will be loaded on the JSONBason side in a table. If you refresh JSONBason, it will destroy the id which stops it working, update the snippet in your code with the new id when you are ready to use it again, newly generated on each page load. Any feedback on this would be awesome, thanks for reading!  ( 5 min )

Common Sorting Algorithms Bubble Sort | Runtime : O(n²) average and worst case. Memory : O(1). In a bubble sort, we start at the beginning of the array and swap the first two elements if the first is greater than the second. Then we go to the next pair, and so on, continuously making sweeps of the array until it is sorted. In doing so, the smaller items slowly "bubble" up to the beginning of the list. Selection Sort | Runtime : O(n²) average and worst case. Memory : O(1). Find the smallest element using a linear scan and move it to the front (swapping it with the front element). Then, find the second smallest and move it, again doing a linear scan. Continue doing this until all the elements are in place. Merge Sort | Runtime : O(n log(n)) average and worst case. Memory : depends. Merge…  ( 6 min )

At first, I joined this specialization out of curiosity — I’d seen it recommended everywhere and wanted to check out its structure. And wow — it turned out to be a solid journey from beginner to intermediate front-end skills. What makes these professional programs on Coursera even cooler is that they’re Foundation for International Business Administration Accreditation (FIBAA) certified and can even count toward academic credits in some universities. This one had around 212 hours of learning across 9 courses! Short, clear videos that get straight to the point. Reading materials that go deeper when you want them. Quizzes to test your knowledge as you go. Built-in code editor for hands-on practice. Loved the AI Coach — super helpful for reviewing topics. The final project ties everything together really well. The course forums felt kind of empty — some people just post random characters to “complete” the task. No mentor feedback from instructors. Projects are peer-reviewed — sounds great in theory, but many submissions are empty files or copied content. Feels like some are only there for the certificate, not the learning. All that said, I think it’s a great starting point if you're looking to get into front-end development. Just make sure to actually build and explore, not just tick boxes. Your growth will come from practicing and creating beyond the course material. View my certificate: Meta Front-End Developer Specialization  ( 6 min )
